Such purchase can be financed, but the loan must be non-recourse according to the IRS rules. 

Tenants tend to stay in SFH's longer than apartment rentals, so I would assume 3-4 years, and turn over could be as simple as a wipe down and carpet cleaning if the PM is doing their job and screening tenants appropriately (although even great screening doesn't always guarantee great, clean tenants).  

Congrats on cleaning up the neighborhood!!

In my experience it should not be your responsibility to pay the lien, it will get paid off prior to or at close.With that said, I have represented buyers and have personally purchased properties off of all the auction sites here in CT and in a lot of the cases the title did not come back clean initially.

I would not show a buyer opportunities without a contract or at least an NDA/non-circumvent in place.

It's simple and clean but at the same time has a lot of capability. 

It's not in too bad shape, but was a smoker's house and hasn't had any cleaning done in years.Based on a quick walk-through I'm looking at internal painting, minimal external painting, carpet replaced (or removed to get to the hardwood floors where possible), a bunch of minor repairs to things like gutters/eaves/etc.In a perfect world, this relationship would continue to care for the property as issues occur in the future.

The house is already clean, it is open for you to have access to it." 

If using a lender this is a non issue.

Speak to all tenants involved and if the problem can not be resolved you have the option of evicting/non renewing the noisy tenants lease.
