The capper, so to speak,  was to spray every square inch of the interior with two coats of Zinger BIN Shellac using an airless sprayer.

@James Brand, Yes we are keeping some of the original features: the plaster walls, which are in great shape, will get a new skim coat, and there are original pristine hardwood floors in the living room.

Put an attractive top coat of paint of the walls and ceiling.

If the cabinet bottoms are still ratty, either cover with a stick-on vinyl or a coat of quality latex enamel once clean and dry.

The one on the left enters directly into the dining room, while the one on the right enters into the living room with a coat closet right there upon entering.  

Porch all fixed up and exterior paint complete plus roof coated, primed and painted. 

& YES I would have a hard time parting with the 0.025% Interest on the escrow account.Last one did an excellent job until he walked away from $6,700 & all he had left was the following for the OP.Basic 3 wood 'contractor' rear steps, gutters & down spouts, audible alarm on grinder pump, 2nd coat on front door & pillars, wiring etc from panel to late a/c install.

You would be surprised at how nice old hardwood floors look after a little scraping, washing and a good coat of wax.

Not sure what they were from, but the Shellac primer covered it in 1 coat with no issues.

Refinish them and use 3 coats of poly.Then do a scratch/recoat every few years/vacancies.
