The same bank offered two rates on two nearly identical files and the only difference was how the income was documented

The example in this thread illustrates something that catches a lot of self-employed borrowers off guard, so it is worth slowing down on the mechanic.

When a lender averages 24 months of 1099 income, they add both years and divide by 24. If year one was $80,000 and year two was $120,000, the qualifying income lands at $100,000 a month divided into the annual total, so roughly $8,333 a month. A lender who allows a 12-month average using only year two gets to $10,000 a month from the same borrower. That difference in monthly qualifying income can move the file into a different loan tier, and the tier determines the rate. The income did not change. The counting rule did.

This is what the thread means by "the guideline is the rate." It is a real thing, and the math above shows why it matters at the numbers the thread used.

The thing worth adding for anyone reading this as a borrower: lender guidelines on income documentation are not posted anywhere easy to find, they vary by lender, and they change. A broker who knows which lenders use 12-month 1099 averaging, which require 24, and which will accept a year-to-date profit and loss statement alongside the 1099s is doing something meaningfully different from a broker who is only comparing rate sheets. Asking your broker "which lenders have the most favorable documentation policy for my income type" before the file goes out is a reasonable and specific question.

I want to be careful here: I cannot tell you which lender or policy is right for your file. That depends on your actual numbers, and a licensed mortgage broker or loan officer is the right person to map your documentation to available guidelines.

What does your income documentation look like, W-2 or 1099, and has a broker already looked at how different lenders would count it?

Ran into this exact wall on a Durham duplex in 2022, my own file, 1099 income two years running but year one was thin because I'd had a slow flip cycle. Broker sent it to one lender, they averaged the years, I didn't qualify at the tier I needed, and I ended up with a rate that cost me roughly $140 a month more than my salaried partner on a near-identical property. I didn't know to ask which months the lender was counting until after the lock.

What you're describing as "shopping guidelines" is the whole job on a self-employed file, but most borrowers don't even know that's a variable, they think rate is the thing to shop and the income calc is just math.

What percentage of brokers in your shop are even aware which lenders on their approved list allow the 12-month 1099 calc before a file comes in, versus figuring it out after they hit a wall?

The 24-month average requirement is the one that kills files and nobody talks about it until the tier drops. I almost used a regional lender on a small commercial conversion last year who averaged my two weakest 1099 years because that was their look-back window, and the income they were willing to count was about 18k lower than what I actually earned in the most recent year. Switched lenders, 12-month policy, same rate environment, came in 40 basis points tighter. The broker had not volunteered that information. I had to ask specifically whether the lender averaged or used the most recent period, and I only knew to ask because I had already gotten burned on a smaller deal in 2022.

What I want to know is whether the 1099 borrower in your example was a first-time buyer or someone who had been through this before, because in my experience a first-time buyer would have just taken the 7.625 and never known the 7.25 existed.

What did the 1099 borrower's year-one number look like versus year two?
