A rock ledge under the driveway nearly ate the margin on my first build
The lot cost me 62,000 cash and the finished house closed at 452,000, eleven months from the first excavator to the closing table. I own a couple of small buildings and I'd never built anything from dirt, so I'm writing this the way I'd have wanted to read it a year ago.
The house: 1,780 square feet, three bed, two bath, one story, on a flat-ish infill lot in a neighborhood where everything else was built in the 1970s and sells fast.
What it cost me:
- Lot: 62,000
- Soft costs (plans, survey, engineering, permits, impact fee): 21,400
- Site work: 33,800
- Vertical construction: 244,000
- Loan interest and fees: 18,900
- Taxes, insurance, utilities during the build: 3,600
- Total: 383,700
Sold at 452,000, paid 27,500 in commission and closing costs, so 424,500 net. Profit 40,800.
A few words in case you're new, because nobody defined these for me. A construction loan funds in draws, meaning the bank pays out in chunks as work gets completed and inspected, not all up front. A CO is the certificate of occupancy, the document from the county that says a person is legally allowed to live in the house. An allowance is a dollar figure the builder writes into the contract for something you haven't picked yet, like flooring, and if you pick something nicer you pay the difference.
The part that nearly killed it: site work was budgeted at 19,000 and came in at 33,800. There's a rock shelf about four feet down running under what became the driveway and the garage slab. Two weeks of hammering, and the bank wouldn't increase the loan for it, so that 14,800 came out of my pocket in a single week. If the shelf had run under the whole footprint instead of a third of it I'd have been writing a very different post.
Second scare: my framing crew vanished for 19 days for a bigger job across town. I had no contractual hold on them. I got them back by paying the balance of their framing draw two days after they finished instead of at the end of the month, which sounds small and was the only thing I had.
What I'd keep: I locked the lumber package price at permit issuance instead of at order, and I wrote a rule that no change over 500 dollars happens without me signing a piece of paper first. Both of those saved me real money. What I'd change is paying for test pits before closing on the lot. That's a few hundred dollars against 14,800.
