Know the house before you make your move.
AcrossTown pulls a home's listing, photos, city permits, seller disclosures, hazard maps, and recent sales into one report on your computer, then gives you the tools to price it, inspect it, and decide. Renting? It checks the rent against the market. Selling or renting out your own place? It prices it from the comps, works out what you'll net, and builds the listing.

Everything a home's paperwork won't tell you at a glance
One listing link turns into a full research file. No more twelve browser tabs, a shared drive of PDFs, and a spreadsheet you built at midnight.
One report per home
Paste a link from Redfin, Zillow, Realtor.com, Trulia, or Homes.com. AcrossTown saves the listing details, full-size photos, and price history, matches the building's permits, and tracks the listing's status, price cuts, and offer date. One click refreshes the listing and permits.
Disclosures, read for you
Drop in the seller's ZIP or PDFs. Documents are split, ordered, and matched to the right property, and inspection and pest findings become a costed repair list with page references.
Comps that explain themselves
Recent sales in the neighborhood are scored 0–100 against the home, labeled by how they sold (pre-emptive, offer date, extended), and adjusted in a value grid.
Map & site constraints
See the parcel on a map with flood, wildfire, earthquake, storm surge, and sea-level rise risk, road, rail, and aircraft noise, wetlands, Superfund and brownfield sites, and nearby schools, in every US metro.
Real numbers, not guesses
Cash to close, monthly cost, property tax after the sale, a repair budget, rental cap rate and IRR, and an insurance replacement cost estimate, each filled in from the documents.
Ask AcrossTown
Ask up to four AI models at once (GPT, Gemini, Claude, and Grok) with the listing, permits, comps, and disclosures attached, and a judge model compares their answers. See the cost before you send, then share the answer to WhatsApp, Telegram, or Slack.

Frequently asked questions
It collects everything about a home you’re buying, selling, renting, or renting out into one report (listing details, photos, price history, city permits, seller disclosures, hazard and zoning maps, and comparable sales or nearby rentals) and adds tools for costs, inspections, value, offers, pricing, net proceeds, rent, leases, and applications. It’s a desktop app, and reports are saved on your computer.
Listings and comps work in more than 580 US metro areas in every state, plus Washington DC and Puerto Rico. Every metro includes its local buying process, like which disclosures sellers owe you and when. Permits are looked up automatically in more than 80 metros, and every other metro links straight to its permit office’s search. Hazard, noise, and environmental maps work nationwide. San Francisco has the deepest coverage, with parcel and zoning checks, assessor records, rent-control screening, and landlord rules. The lease, deposit, and move-in condition checks follow California law.
Yes, all three. Renting mode compares the asking rent with nearby rentals, adds up move-in costs, reads the lease, and tracks your applications. Selling mode prices your home from comps, estimates your net proceeds, ranks listing agents, and compares offers. Renting out sets the rent, runs the economics, screens applicants, and publishes your listing to five rental sites. Every mode is included in every plan.
See every mode →No. Every tool works on its own. When you want a second opinion, Ask AcrossTown sends your question with the listing, permits, comps, and disclosures already attached, using your own Gemini, Claude, or ChatGPT account or the AI credits included in your plan. Pick one model, or ask up to four at once and let a judge model summarize where they agree. Every plan includes GPT-4.1 mini and Gemini 2.5 Flash; AI Plus adds GPT-5, Claude Sonnet 4.5, and Grok 4.
Yes. Link WhatsApp or Telegram in Settings and send any answer to your phone. Or link a Slack channel, where each address gets its own thread with the research attached, and anyone in the thread can @mention AcrossTown with a question while walking through the house. Follow-ups are answered from the thread and charged to your AI credits.
Yes. A sample house for sale and a sample apartment for rent come with the app, along with guided tours of each mode, so you can explore every tool before pasting your first link.
No. It helps you ask better questions and catch problems early. Estimates like the insurance replacement cost, repair budgets, and hazard maps are general guidance, not professional advice.
