The only things I change are that I require a copy of their housing voucher (which tells me which agency they're with, how many bedrooms they're qualified for and if their voucher is still active) and I require only 1 months rent in income instead of 3.The rest is the same - I call every landlord they've had for the last 5 years, I check their background, credit, etc. 

Things like income documentation, background checks, credit reports, etc mean a lot more to me.

This was not on credit history but on chain of title. 

If your tenant has a history of failed payments, we permanently move to 3 day holds to ensure the funds are available.

Your offer should have included a requirement that the Seller transfer all tenant documents (application, payment history, lease, addenda, etc.), spare keys/openers/codes, prorated rents based on the day of closing, security deposits, and anything else pertaining to the rentals and tenants.

My husband and I have W2 income and excellent credit and no debt except our mortgage. 

At this point, I would recommend having a line of credit to cover these things so you don't have money sitting in the bank doing nothing when it could be put to work.I have 33 units, no debt except for mortgages, and excellent income.

Most DSCR Lenders will require the property to be rented for a refinance (or if used as an STR for example, have some STR history)  You may be able to find an option for refinancing prior to leasing, but it will make it more challenging and will likely need a "good reason" more than just speed3.

Scammers may even go as far as creating fake W-2s or other tax documents or advertise fake tax credits to lure in taxpayers to share their sensitive information.Text, Mail and Phone Schemes: Scammers are targeting tax professionals and taxpayers through phone calls, text messages, and even fake AI generated IRS letters.

Verifying last 2 years of rental history very important!
