And BP is a fantastic resource, but let's be honest, what you are looking for is WAY too much information to pass along through a forum on the interwebs....

If  you haven't fulfilled all loan obligations I would entertain "roommates" if it is condusive to your living arrangements. 

The owner just passed away, and the house is in a trust.

I would go to the county courthouse and file a claim in the court of record against them for their tress pass upon your property. 

My house in the same county is worth about $290k with $1100 in annual property taxes.I have passed on a number of properties because of the tax implication after converting them to rental properties, particularly in Columbia, SC where dealing with City & county taxes both at the non-homestead higher tax rate simply murders cash flow.

All investors would pay 5% for asset and property management, of which we'd likely pass 3% through to 3rd party property managers.    

How do you pass on the costs to the tenant?

I have taken and passed both the national and state exams.

Made the no interest loan pretty expensive - I passed.

Perhaps you can do a complimentary deal with their SDIRA/401k and you acting as manager.Will this pass IRS scrutiny?
