About to spend your savings on a deal?
Don't guess.
DealUnderwriter is the plain-English deal analyst built for regular people buying their first rental property, small business, or restaurant. We run the numbers a pro would run — then explain every one so you actually understand what you're signing.
What are you looking at?
Pick what you're thinking of buying
Three deal types, each built around the specific numbers that make or break them.
Rental Property
Thinking of buying a rental house, duplex, or small building? Find out if the numbers actually work — before you spend a dime on inspections.
Small Business
Looking at a cash-flowing business on BizBuySell? Learn what it's actually worth, how much you'd pay out of pocket, and what could go sideways.
Restaurant / Bar
Food business for sale? We run the math on covers, food cost, labor, and rent — then tell you if the owner's asking price is fair or fantasy.
How it works
Three steps. No Excel. No jargon.
You bring the deal. We do the math and tell you what it actually means.
Tell us the deal
Asking price, rent or revenue, and a few honest numbers. Five minutes. No spreadsheet. No finance degree required.
See the real picture
We run the math a professional would run — then explain every number in plain English. Find the catch before you write a check.
Get a straight answer
Buy, negotiate, or walk away — with the one number that decides it, and a memo you can hand to your lawyer, accountant, or lender.
Who it's for
Built for the person about to spend real money
Most deal-analysis tools were built for MBAs and brokers — and they look like it. We built this for the person who just found a listing, has the savings to buy it, and needs someone to honestly tell them whether the numbers work. If you're a pro, you'll find it faster than your usual model. If you're not, you'll finally understand what your usual model is saying.
