Thought about if I did scale to say 100-200 doors that I would hire another company to audit the current PM on how they're handling my properties. 

I do bot believe i have the personality or systems for it!

I kind of didn't want to mention that on the listing so that it wouldn't turn people away before they even had a chance to see it in person.  

If you close with a conventional loan, it will need to be in your personal name.

Your plan to handle the strategic aspects remotely while a property manager handles onsite issues is smart, and as long as you log your work and stay hands-on, you’ll likely qualify for active status.

A more realistic expectation is 24 hours which will ensure we can arrange any repairs or corrections with a team, handle it in person, etc. be curious how this plays out as I worked for local developer for a while and developed several properties in Alexandria (Specifically old town) and while the city is challenging like any city - they were mostly realistic.

Some used more creative ways to handle the needs but it is still a capital call and dilutes the return (if anything left). 

The Landlord will verify that the rental is empty of all personal belongings and trash and that there is no damage beyond ordinary wear and tear. 

So, things change a bit.If it is his personal home, there are more restrictions.For an investment property, if you take over his financing, read through the deed of trust (mortgage) and see how they handle transfer of ownership.

You are going to send your wife to personally unclog that toilet.
