A safer bet if the market was to turn.  

For every 1 landlord trying to do it right you can bet there is 1 that doesn't' care, just putting a body in.  

Looks like a safe bet to go ahead and enter and regain possession of your unit.

Your best bet though if you're looking at those types of opportunities will be to research properties that are owner-occupied and their business is struggling and/or are delinquent in taxes, mortgages, and other liens.

Win Win!!

I think that is the safest bet as I'm still able to cash flow based on numbers I've run on how much it would cost to finance the conversion and the rental value I'm currently getting on a room with a private entrance and private bath.

So overall a win, even though it was painful at the time.

Would like to know if you are the winning bidder of a lien with a mortgage filed, after the 4 year period what would happen to the mortgage.

Win-win-win at the highest level. 

Since I work with realtors so much, I bet I could do the listing myself, but still will probably hire a listing agent.
