Living in one unit while tenants pay the mortgage is the cheapest way into real estate, but only if the other units cover enough. House hackers who run the address first know what they will actually pay to live there before the lender asks for documents.
Free Discovery. No signup. No card.
Sample Discovery. Yours runs on the address you enter.
The house-hack snapshot uses low-down-payment terms and shows your effective monthly housing cost after the other units’ rent comes in.
Live rent estimates for the address, scaled to the units you do not occupy. The difference between that and the payment is what the house costs you each month.
When you move out the property becomes a full rental. The long-term rental snapshot sits beside the house-hack one, so you know what it turns into before you buy it.
Paste any US address. Multi-source value, a rent estimate, the Deal Gap and six strategy snapshots come back without a signup or a card.
Zillow, RentCast and Redfin estimates are pulled live and blended into one IQ Estimate. Every source stays visible. When one has no data for the address it reads unavailable; nothing is made up.
Asking price minus the price that works. That one number is the offer conversation, and it is on the screen before you have spoken to anyone.
A price cut, a capital ask, a financing change such as seller carry or a 0% second, or a blended plan of smaller asks that reaches the same math. Each is modeled on this address.
Property tax, vacancy and appreciation for every state are on the /markets pages and shown in every Discovery. Pro lets you edit them per deal and watch the math change.
Paste the address. The house-hack snapshot is part of free Discovery, no signup and no card.
Free Discovery. No signup. No card.

What Early Users Are Saying
“I used to spend 45 minutes per property on a spreadsheet. DealGapIQ gives me a better answer in under a minute. The Deal Gap concept alone changed how I evaluate deals.”

“The Income Value calculation is something I’ve never seen anywhere else. Knowing exactly where breakeven sits — before I even tour a property — saves me from chasing bad deals.”

“I was skeptical of another calculator tool. But seeing the actual assumptions behind the numbers — and being able to change them — that’s what convinced me to pay for Pro.”
