I always check previous landlord and rental references, and call the HUD office for a character reference as well.

The police did not arrest her the 1st time.

Should my interior design business purchase a multi-use space where I could have our office and rent out other spaces?

If a tenant comes in to pay multiple charges with one payment, my office manager has to get out the pen and pad to figure and place individual payments instead of something similar to Quickbooks where you enter an amount paid and select which invoices you want it to apply to. 3.

They are both in demand, and appear to be growing, like multifamily.I would stay away from office and nota big fan of retail strip centers. 

Before you assume that go to your local section 8 office or talk to some locals and see if that is even feasible. 

I've had to get rid 3 people for non-payment this year but in my area rooming houses are run like a hotel so we can just tell them to leave and/or call the police if they don't want to go nicely.

Even though the property is under your Nevada LLC and you're the managing member, the lender will still need to be involved to ensure everything is cleared.Make sure the title transfer was properly recorded after your ex-spouse's passing, and work with your escrow officer to handle the mortgage at closing.

I would probably be still working as an AZ State Corrections Officer making $20hr and I wouldn't have my rental portfolio if it wasn't for my 0% down VA loan, FHA 3.5% and Fannie 5% down.

Not sure on the $400k, but I can put you in touch with my realtor and others in her office.
