For real estate agents
Put real numbers in front of your clients
Homeowners, sellers, and investor buyers all ask the same thing in the end: what does this mean for me? RE Underwrite Lab gives you the calculators to answer it in the room, and a report to leave behind.
What you get
Client-ready numbers in minutes
Type in what the client tells you and get a clear answer on the spot: the payment, the net, the break-even, the cash flow. No spreadsheet to build, and nothing to install.
Speak your investor clients' language
Cap rate, cash-on-cash, DSCR, BRRRR, and flip profit are all here. Run a listing the way an investor will before you send it, and show up to the showing with the math already done.
Reports under your name
The cash-out refinance and seller net sheet calculators print a one-page client report, with your name and company if you add them. Pro PDF reports carry your name, and flip and short-term rental packets also take your company, phone, email, logo, and a property photo.
Faster listing and buyer conversations
A seller net sheet at the listing appointment. A payment and cash-flow check before the buyer falls in love. A refinance comparison for the past client who keeps asking about their equity. Numbers move a conversation forward.
Calculators for client conversations
All free to use, no account needed. Each one prints or saves as a PDF.

Where it fits in your week
1
At the listing appointment
Open the seller net sheet with the seller's payoff and your terms. Show the net at the price, at 5% under, and at 5% over, and the price it takes to hit their number.
2
With a past client
A homeowner with equity and a stack of high-rate payments? The cash-out refinance calculator shows what one payment would look like, so the next step with their lender is a confident one.
3
With an investor buyer
Run the rental, BRRRR, or DSCR numbers on a property before the showing. The client sees you know the math, and you spend time on deals that work.
