One boiler, one water meter, and utilities take 22 percent of gross

The thing that jumps at me is that every option on your list is a project. Converting four heating systems is a project. Rewriting four leases with a utility share is a project, and it is a project you repeat every year with every new tenant. I came into this size of building wanting income without a second job, and master-metered buildings are where that wish goes to die.

Which is fine if you want the work. But price the work. Forty thousand of mechanical plus your time, against 12,840 a year of utilities that you would only partly recover, because you still pay for the vacant unit and the common areas either way. If the conversion takes 7,000 a year off your bill you are looking at a long payback and four units of disruption.

What does the 460k version net you if you change nothing and just accept the utility line as the cost of owning a 1962 building?

I own a triplex that was master-metered for heat and I converted it, so I can give you the real version of that decision.

Mine was a 1950s building, one oil boiler, three units. Quotes came in between 29k and 41k for three gas furnaces with new venting. I did it at 34k over two turnovers, one unit each summer, and the third unit's tenant stayed through it with a week of space heaters and a rent credit. My heating bill went from about 5,600 a year to about 400 for the common areas. So the payback on paper was five and a half years and in practice closer to seven once I counted the credit, the vacancy I extended by two weeks, and the drywall patching nobody quotes for.

Was it worth it? Yes, for two reasons that are not the payback. The building stopped having a single point of failure that could take out all three units in February. And when I refinanced, the appraiser's expense comparables assumed tenant-paid heat, so the separated building read as a stronger asset.

Water is the harder one. Splitting a water meter in an older building often means opening walls, and in my case the plumber priced it at more than the heat conversion and I passed. I bill a flat water and sewer amount into the rent instead, which is legal where I am and is not everywhere, so check your state and city rules before you write it into a lease.

Do not do all four units in one season. You will hate your life and you will not have a vacant unit to work in.

Buy it at a price that works with the boiler in place, then convert on your own schedule as units turn. Two leases expire in April, which is exactly when you want a unit empty for mechanical work.

I would not spend 40k in month one on a building I have owned for four weeks. You do not yet know what else in a 1962 fourplex wants money, and the first year is when you find out. Patience costs you 7,000 of gas next winter. Impatience costs you your reserve.

If you do decide the conversion has to happen sooner than cash flow allows, the money for something like this usually comes from somewhere other than a bank. I have been sitting in on how private capital gets placed and a 40k mechanical upgrade on a stabilized fourplex is a small, unglamorous ask that private lenders sometimes like precisely because the collateral is already producing.

The part I would think hard about is what you are promising in return. Anything that involves other people's money for a return has securities questions attached and that is a licensed professional's call, not a forum's. A straight loan secured by the property is a different animal from taking in a partner, and the difference matters more than the interest rate.

Cairn's point about the appraiser treating a separated building differently is the one I would chase. If the conversion moves your value on refinance by more than its cost, the timing argument changes.

Two years of bills averaged is hiding something I would want to see. What were the individual months? A single boiler serving four units in a cold market can produce a January bill that is four times the July bill, and the average tells you the annual cost while the monthly spread tells you what your worst cash flow month looks like.

Also, were the two years similar? If one winter was mild and one was hard and they averaged to 7,140, your bad-year number might be 8,600. I would model the bad year, because that is the one that decides whether you can hold.

And on the water, 4,980 on one meter for four units. Do you know whether there is a running toilet somewhere in that number? Master-metered water hides leaks by design, and I have read of people finding 1,200 a year of waste on the first walkthrough with a plumber.

Coming from zero here, so a basic question. When people say billing tenants a share of the actual utility cost, what does that mean mechanically? You get one gas bill for the building, then you divide it somehow and add it to each tenant's rent?

And how do you divide it fairly when one unit is a one bedroom with one person and another has four people running laundry every day? I can see why a tenant would argue with the math, and I can see why that argument would land on you every single month. Juniper, if you go that way, what is the actual document that tells a tenant how their share gets calculated?

Ember, the general name for it is ratio utility billing, where the building's bill gets split by a formula, often by square footage or occupancy. Whether you can do it, and how you have to disclose it, varies by state and by city, and some places restrict it outright, so that is a question for local rules before it is a question for your lease template.

Juniper, the failure point is what I would fixate on. I run a small portfolio and the lesson that cost me most was concentration of systems. One roof over four units, one boiler over four units, one main sewer line. When one of those goes, you are not solving a unit problem, you are solving a building problem, and every tenant is affected on the same day.

A 2004 boiler with 21 years on it is not an emergency and it is not a long runway either. If you buy at 520k with that boiler, I would want the full 40k sitting available and untouched, which is a different question from whether you spend it now.

This deal is an active project wearing passive clothing. Forty thousand of mechanical, four lease rewrites, a water meter question and a boiler at the back end of its life. That is a value-add repositioning at a 4.3 going-in cap.

Which might be exactly right for you, I have no idea. But I have been trying to sort out which strategy actually fits me and the thing I have learned is that people buy the asset class and then get surprised by the job description. A separately metered duplex with a newer roof is a passive holding. This is a two-year project that ends in a passive holding.

If you want the project, the 460k offer matters more than the conversion plan, because the price is where you get paid for doing the work.

I have been building a list for a year and master-metered buildings are one of my two main filters, for the opposite reason to everyone here. They are how you find a discount in a market where nothing is discounted.

Sellers of these buildings quote gross rent and buyers who copy a single family expense model get to your exact spreadsheet problem, then either overpay or walk. The ones who walk leave the building sitting, and a building that has been sitting is a building where 460k gets a conversation.

So I would go back at 460k and mean it, with the mechanical quote and the two years of bills attached to the offer. He refused once before you had documents. Refusing a number is easy. Refusing a number backed by a contractor's letter and 24 months of gas bills is harder, and if he still refuses you have learned the price of his patience.

Juniper, out of curiosity, how long has it been listed?

Before you build a plan around billing tenants for utilities, read your city's rules on it, because in some jurisdictions the practice is limited or requires specific disclosure and in others it is fine, and this differs by state and often by municipality. The lease language people copy off the internet is written for whatever state the writer lives in.

The other local item is the mechanical work itself. Converting one boiler into four heating systems in a 1962 building usually means permits, new venting through the exterior, and possibly a gas service upsize from the utility. I have watched a similar conversion stall for five months on a utility service upgrade that nobody put in the quote. Ask your contractor in writing whether the existing gas service can carry four furnaces plus the water heaters, and get the utility's answer before you commit to a schedule.

Orchard's sequencing is the part I would keep. The April vacancies are worth more than the interest you would save by doing it all at once.
