Mom was a Resident manager.

As mentioned it can cause parking issues and noise problems for the other residents.

Live in this house for a year or two and then turn this home into a rental, and purchase another primary residence.

They were both live-able and for our primary residences at the time so we used conventional financing.

(Not counting my residence of course).

For example, suppose you want to pay a resident manager to also manage your second property, or you want to hire your retired brother-in-law, who lives in his own home, to manage your apartment complex. 

I would rather renovate a rental and be able to take the depreciation instead of renting my primary residence unless I am missing something.

Greetings,I am stuck and would appreciate some advice on which avenue to take regarding the financing on my next primary residence.

But, I have formed a partnership with someone who still has 9 left (he owns his personal residence).

If it is a single-family residence, it must remain a single-family residence.
