I echo what @Jon K. said... if you're still interested after doing some additional due diligence, try starting with 1-3 as opposed to jumping into 10.

Have some quotes going the DSCR route however fees and rates seem on the higher end, we have 790 credit score, good W2 jobs so documentation is not a problem and we don’t have an issue putting them in our personal names, but have had the MFRs for less than a year and operate out of MD.

If credit is healthy and the property performs from an income standpoint you may be able to go up to 85% on this transaction. 

What sort of additional documents can I request?

10% down, 30 year amortization, 6.2% rate, 3 year note, with an option for an additional 3 years.

It’s simple/cheap to execute and makes filing for taxes easy for them because it’s just an additional 1099.But, I don’t love that they’re all in different positions, or that their names are now attached to the title report.

Additionally, I recommend reaching out to @Kyle Mast for his perspective.

Certain income and credit requirements may apply for access to these programs. 

Maybe agreeing to a % from the sale of each home in addition to listing the homes once the construction starts?   

In addition, because their rent is high tenants don't stay as long further increasing the vacancy time by increasing the frequency of turnovers.
