I understand this is not a requirement, but I have never received a damaged unit from an inherited tenant or any legal issues.

If they did not provide a forwarding address we send it to the unit address, hoping they filed a change of address form.

I personally use the mass text capabilities through my Resident RE CRM.However I have a few friends who wholesale and invest and use Mobile Monkey to mass text and from what they say the price is pretty reasonable.

Ask how many units they manage and how much experience they have.

Investment Info:Large multi-family (5+ units) commercial investment investment.

You'll find more 2-5 units in some of the older parts of our city right outside downtown. 

For comparison purposes, I hold ownership units in a LLC that owns a retail/service center where there is a mortgage loan that initially represented 50% of value, now about 35%.  

As for valuation, I see no reasons why a Junior ADU would negatively impact additional housing unit.

A lot of qualifying questions for any potential tenant.Having said the above, I ask for some "standard" things, such as the names of everyone who'll be living at the unit.

But, the self-sufficiency test for FHA loans can be really difficult in SF, meaning that the market rent from units you will not occupy must be sufficient to pay for the mortgage payment.
