If you're looking in Ohio, I can recommend hitting up Kurt Weil. 

I would recommend finding a real estate tax specialist.

Any recommendations for that?

I would recommend speaking with @Denver McClure as he could provide some insight into this.

Quote from @Ben Trageser: I would recommend calling the zoning department of the town and asking.

I work with a lot of house hackers in the Denver Metro and constantly get asked for recommendations on PM's that handle rent by the room. 

(Any lender recommendations?

I recommend you pay him the final amount, but get a lien release, in advance, that says if you pay him this final amount, he will have been paid in full for his work and no further liens can accrue.I believe a mechanics lien once filed generally initiates a court date to substantiate the claim.

I'd recommend the spread on the return and your ability to replace damaged items (local vs. not local, strength of your team) be the determining factors in that decision.

We also recommend GK mngt, Evernest, Camelot, Renter's Warehouse & Gateway.
