I know many airbnb owners cashflowing even while house hacking!

-More targeted prospecting like Absentee Owners, FSBO, etc: its ok to leave a VM/text, you can say something powerful like "are you the owner of 123 main st?

Have your husband( as owner, ceo, whatever) of the construction entity agree to perform Cost-Plus contracts with the Holding LLC, as an outside contract. 

A property owner may need a roof on their house they can't afford.

If you take the owner financing and it is paid off shortly you will have a large tax burden at that moment. 

Otherwise S-corp 1 owner. 2.

If they are paying, keep them on month to month.Our renewals 60-90 days before the lease ends....say something like your current rent is $1500, we are increasing rent to $1550 starting June 1st....and you as the owner get to choose one of two options....continue month to month at $1750/month, or sign and return 1 year extension by April 10th, or option 2, your lease will end on 5/31.I say do everything you can to keep tenants that pay. 

Just make sure however you sell it is to an owner occupied and not to a mobile home flipper who will pull the home, resell and relocate. 

He agreed to selll to me for 88K, rent to own for 4 yrs with 10% down paid in 200 dollar installments and owner financing.

The "first lien Alt-A loans" covered our first lien on non-owner occupied LOCs.
