Generally, only 1 or 2 years of  business and personal tax returns (depends on how long your business has been around) should be the only additional docs needed for most self employed vs W-2 wage earners.and the items mentioned above are not relevant for a qualified borrowers (and some are down right incorrect). 

There's a price/rent lag because leases are typically for a year so there's the delayed effect of old leases playing out before upward pressure on rents does it's thing.With that said, there's also your ability to refinance out of that rate and improve the rentability of it that way.

I'm currently 23 and have access to around 40k liquid to buy a home when my lease is up in March of 2025.

That's why I was leaning to foreclosures so I can do full cash (heloc) purchase.The other part I need to get more fluent in is how to document all of those action items in the LLC to keep the corporate veil. 

I want to see what the rental rate would be for a NNN lease based on the CAP rate.

Her medicaid and SNAP applications have come to my house and she lost her job and multiple lease violations in the few 5 mo she was here.. 

Full renovation in 2023 and re-leased at higher rate.

I wouldn't call that a true "DSCR Loan" - especially considering that a ground-up construction property won't have any cash flow so DSCR would be negative or 0 numerator if you'd try to calculate it ground up multifamily is not 0 cashflow there are hundreds of thousands of apartments built every year, leased up, and sold for a profit as well. we build not only at a discount for investors but 1% on infill lots I'd be really careful with all your absolutes. you can get land for 10k in columbus on lots you can build 2-4 units on in one of the cheapest construction markets in the country.

The code I have been quoted says "Whenever any person, whether as the owner or agent for the owner,rents, leases or has available for rent or lease, one or more residentialunits, such person shall be deemed to be in the residential rentalbusiness."
