At the listing appointment

A seller net sheet for realtors — and a listing presentation calculator

Sellers ask one question: what do I actually walk away with? Enter the price, payoff, commission and closing date and answer it while you're still at the table. State-specific transfer tax, title and recording assumptions are pre-filled, and you can override any line with local numbers before you send it. Numbers recalculate as you type, so it works on a phone at the kitchen table with no spreadsheet to set up. When the seller is ready, send the report before you leave the appointment.

With an investor client

Buyers comparing rentals need more than a monthly payment. Show cap rate, cash flow and cash-on-cash side by side, then send the analysis as a branded PDF or a secure link they can read on their phone before they write an offer.

Can I use this live in a listing presentation?

Yes. Results recalculate as you type and the layout is built mobile-first, so you can run the numbers on a phone at the kitchen table.

Can the report carry my branding?

Estate Pro puts your name, photo and brokerage on every PDF and every shared link. Your one free Seller client package also carries your branding; ordinary free shares carry a small Sumline credit.

Does it use state-specific closing costs?

Yes. Transfer tax, title and recording assumptions are pre-filled per state, and every field is editable before you send anything.

Do I need to set up a spreadsheet?

No. There is nothing to configure — open a calculator and start typing.

Can my client open the report on a phone?

Yes. Shared reports are read-only web pages that open on any device and print cleanly.

Can I put a calculator on my own website?

Yes. The Partner plan ($49/month, 30-day free pilot) embeds a co-branded lead-capturing calculator on your site. See /partners.
