All have different guidelines surrounding what you must use for qualifying payments.With deferred loans, however, it's pretty consistent that you must use 1% of the balance as the qualifying monthly payment.One work-around is to go on an income based payment plan.

I am looking to put down as little as possible to increase cash on cash return and have money left over for reno.

I'd even be willing to make a small wager that honestly reported he is making maybe 2- 3%/ year on that property as an actual return if he hasn't kept up with rent increases. 

Voter-approved bonds can increase the 1% base rate, such as bonds providing funding for schools, parks, or other community services.

Shared tenant monument signs generally they do not have rental increases so the cash flow stream counted in the NOI diminishes year over year in value.

To keep things simple, we stay consistent with our percentage ownership in everything and that is reflected in our K-1s.For additional work I've done for our LLC, we will pay me "management" or "services income" and I get 1099's at the end of the year.
