Thanks so much for the response.

I suggest you develop a fairly detailed scope of responsibilities for that PM, including how often you expect him to be there and exactly what kind of interactions, inspections, reporting and other activities & responsibilities you expect of him. 

Anything secured against the property will be paid off (it may be a partial pay off depending on negotiations with your lender) but you will still have the responsibility to not only use all of the cash in the next purchase but also to purchase at least as much as you sell.So, if you've had to make a partial payoff to sell the property you'll either have to replace the debt or bring in cash from somewhere else to meet your 1031 requirements.

I appreciate your response!

After all that is complete, then it makes sense to spend money on the inspections, surveys, contractor bids, etc.

There is a debt that my ex-husband is responsible for that is affecting that.

Explain to them you will do your best to find a replacement tenant at the same rent they were paying, but they are responsible for their rent until such time that you find somebody.

I look forward to your response. 

Who is responsible in this case?

Thank you @Seth Lipper for the response.
