There was another known heir the passed with no children to pass her ownership to and a few others that can’t be located. 

Yep, court awarded child support against unmarried partner (live ins that broke up) for children they didn't sire.

A benefit to having the commercial property and entity is that we aim to utilize business credit, so that our personal credit and debt to income ratio is not tanked as we remodel or redesign or buy furniture. 

You do not need to have a license to manage an apartment community.Property management can then be broken down into "annual" property management (normally a unit without furniture), a seasonal rental management (such as 2 weeks to several months up to 6 months) and then vacation rentals (sometimes for the weekend, a week, etc..).Each state has its different rules and licensing for each area of property management (annual, seasonal and vacation) as well as the different areas of management (association, apartment and property).I hope that helps.My understanding is that if you are an EMPLOYEE of the property owner you do not need to have a license; if you provide property management services as your management co owned business or as an independent contractor, then you do need a license.  

Many of them don't have a lot of cash reserves if they're paying high mortgage, rent, have children etc. 

If I could find a TRUE cash flowing property in my market that cash flows $200/month after all expenses and reserves I would sell my car, wedding ring, cash in my children's 529s, sell one of my kidneys and buy everything I could. 

The new tenants, starting their lease on September 1, have asked to move their furniture in earlier.Can the current tenants request the keys back since their lease isn't over until August 31?

But sounds like you have old furniture in the house? 

For items like decor and furniture the cleaners have to match photos of new stay against previous stay room by room with photos and the EZCare App.
