Section 8 can provide a steady and reliable source of income from government-backed rent payments, but with that said, make sure to do your research on the local market to ensure demand, and be prepared to meet the property standards required by the program.

You can also use a standard board of realtor lease template.

Many lenders will consider this commercial use, so a standard DSCR program will not lend to it. 

Dimensions and layouts on these are mostly standardized so you shouldnt have any problem unless the existing cabinets are custom built for the space.

I do the standard buy and hold but the property has to be bought at a discount - 85% of ARV is my maximum - including purchase price and rehab.

Should be fully upfront and aim for a property that could work just as easily as a standard single family rental too

Here is a standard clause from the Columbus Realtors you can use to protect yourself:111 Investment Property Purchase ClauseThis Offer is contingent upon Buyer’s satisfactory review of all leases, rental agreements, deposits, past _______ years’ income and expense reports and within ___________calendar days after acceptance of this offer.

Setting standards just to deny people is BAD practice, BAD business, and ILLEGAL.

I agree with this high level (Private Money = Individual, Hard Money = Company Non-Turnkey Product).I've been begging (mostly to no avail) for better clarity and definitions here for these to avoid confusion - BiggerPockets IMO has a HUGE opportunity to set and create the "gold standard" universal definitions of loan types with just a little initiative. 

You’ll also need owner and lender's title insurance as well as the standard fire and liability coverage, which I assume you already buy.
