Four pages. Your property, in plain language.
- Your parcel and your city's rules, translated
- How much of the lot you could build on, and what sizes may fit
- What it might cost, and what it could do for the property — with sources
- What to do next, and what only a site visit can settle
A preliminary estimate from public records — not a guarantee of approval, value or final cost.
The home you own is usually the key.
Equity you already have
A home-equity line or a cash-out refinance, drawn as the build goes. The most common route.
A renovation or construction loan
Lends on the finished value, pays the builder by milestone. Fewer lenders, more paperwork, bigger projects.
Rent that pays it down
A second home on the lot can carry part of its own cost. The report shows sourced rent context for your area.
HousUp isn't a lender and doesn't take fees from one. If you want an introduction to a lender who does this kind of loan, ask — only with your say-so.
Read before you decide.
What could your lot hold? A checklist
Eleven things worth checking before you spend money on anyone’s design: access, slope, trees, easements, sewer, and the four rules your city sets above the state floor.

From a free look at your lot to the keys: the seven stages, about how long each one takes, how the money moves, and the three points where the decision is still yours.
Read →Is this really free?
Yes. No obligation, no sales call. The report is yours whatever you decide.
Who builds it, if I go ahead?
HousUp doesn't build. If you want to go further, HousUp introduces its partner builder for your area — only if you ask. The fixed price and the construction agreement come from that builder, after a site visit and a design, and you're free to use anyone.
What if my lot doesn't have room?
The report says so, plainly, and shows what might work instead — an addition, a conversion, an upgrade.
I'm working with a real estate agent. Does that change anything?
Your price doesn't change. If your agent sent you, the report goes to you both, and your agent stays your agent.
