You first want to know that those framed out "units" have the proper permits, zoning, etc.

To me... taking 1 hour out of my time (including driving time, coordinating, correspondence), paying for gas and vehicle maintenance to drive to properties, taking videos, taking photos, filling out a property checklist, compiling it all to email it forward -  for $20 doesn't really make sense.

Like all channels of marketing- it starts with the proper list and content.

How do I put the mortgage in my name but assure that the house still goes through the proper channels if I were to die? 

I would front the funds for a scheduled portion of the work, they send someone to inspect and verify that it's done properly, then they reimburse me for that portion so that work can continue.

To have good credit you must have and manage debt properly.

Well I’m a complete newbie and own one properly already (the one I live in).

And, if you properly calculate all expenses, including depreciation, your properties may generate a tax loss, which can even help offset your W2 income - I believe this deduction is up to $100K in income, and then phased out between $100 and $150K. 

I self manage (for now)  owner had the property for 20 years, didnt manage it well, no one is screened properly. my wife and I must occupy the property so one must go. this is a class C community. inspection shows the systems and roof of the home to be in good shape. what would you do?
