.* Criminal History.

One on eastern side connected to the main st in Higginson.

If you're specifically wanting to focus on the Eastern Kansas side that is within the KC metro, Johnson County would be a great starting point to look into (Overland Park, Mission, Roeland Park, Olathe, Prarie Village, Leawood, Shawnee to name a few).

One other question if possible any leads on great credit repair services you used or know of they work history.

Or they can see old wiring and suggest you hire an electrician for a more in-depth review of the electrical system.If the property is occupied by renters, you should review their leases, payment history, applications, and anything else you can get your hands on.

What documents do they require, what credit scores do they allow, how do they verify previous rental history, etc.?

Look at the repair history. 

Most lenders do not use proposed short term rental income when you have no history on your IRS taxes to show the higher rent, they ask the appraiser to come up with a long term rental survey (you pay for this about and extra $200) and that minus 25% expense ratio is compared to the principle interest tax and insurance payment of the propose purchase plus your total housing PITI as if you drew 100% of the HELOC at the maximum rate plus car, credit cards, student loans etc...You need a lease and a deposit payment banked in your checking before docs.No it is not likely or "believable" that your spouse is buying another owner occupied home unless: you can show you are divorcing thus you need divorce decree and whatever expenses from that mess.

What documents do they require, what credit scores do they allow, how do they verify previous rental history, etc.?

@Radley BuxtonI have lenders who will allow us to use Airdna data but the borrower needs to have experience with owning a STR of the property needs to have a 12 month history.
