Plat Book

Every lot in Oklahoma City, and whether it pays.

Plat Book puts the city’s zoning, lot lines and flood maps next to a simple deal calculator. Tap a lot to see what it’s zoned for, then find out in a minute whether a property would pay for itself.

From a lot to a decision in three steps.

Most of what you need to size up a property is public, but it’s scattered across city, county and federal websites. Plat Book gathers it in one calm place and does the math for you.

  1. Find a spot

    Search an address or tap any lot. You’ll see its zoning and flood zone, straight from the City of Oklahoma City and FEMA, over a street, satellite or plain map.

  2. Run the numbers

    Enter the price and what it would rent for. Plat Book tells you in one sentence whether it pays for itself, and what rent or price would make it work if it doesn’t.

  3. Keep your list

    Save every property you look at and mark where it stands, from watching to owned. Your deals show up as pins, so you can see your whole search on one map.

Two ways to buy your first place.

Switch any deal between them and the numbers rework themselves.

Rent it out

Buy a house or small building and lease every unit.

See monthly cash flow after every cost, your yearly return on the cash you put in, and how it holds up if rents drop, rates rise or a unit sits empty.

Live in one unit

Buy a duplex to fourplex, live in one unit, rent the rest.

See what it costs you to live there compared with your rent today, and what the building earns once you move out. Owner-occupied loans can need as little as 3.5% down.

Every number comes with a plain-English explanation. Tap the question mark next to it.

Your deals stay with you.

There’s no account and no server holding your numbers. Here’s what that means in practice.

  • Deals save in your browserNothing you type is sent anywhere. The map asks public city and federal servers for map pictures, and that’s all.
  • Save to a file to back up or shareOne tap downloads every deal as a small file. Text it to a partner, or keep it somewhere safe.
  • Load a file to combine listsNew deals are added. If you both have the same deal, the copy edited most recently wins.
  • Clearing your browser erases themSave a file before clearing history or switching browsers.

Where the map comes from

Zoning and lot lines appear once you zoom in to street level.

Arithmetic, not advice

Plat Book calculates from the numbers you enter. It isn’t financial, legal or tax advice, and its starting numbers are only examples. Before you make an offer, get a real rate from a lender, a real insurance quote and the actual tax bill, and confirm zoning with the city and flood status with a survey.

Pick a street you know and start there.

Tap a lot, run the numbers, and see what you learn.
