(salt water melts iced goo quicker).i would replace/reset the wax ring (they also make waxless now: rubber cone or foam type). i like to use 2: one is the oversize one, and a regular one to "butter" around any gaps to the connecting tile floor.i would use some lye (about twice per year) (please no drano) or baking soda and vinegar left to bubble followed by large amounts of water.extreme DYI: use a dry/wet vacuum on the push (NOT pull) setting

Are their any websites out there that could help me identify which town(s) have the most renters or is there demographic information that I should be looking to use as a guide?

Because as a non-carpenter, my decision was to shave the door, which looked like crap, was not a straight line (lack of tools) and sucked more of my already stressed time....

I have been thinking I'll have to force cash out of projects by adding units or shaving off and selling/developing buildable land.What solutions do you see?

First spray foam inside holes then apply 1-2 coats bondo over for a smooth finish. 

we took about 5 bids.....one of them used foam and it was not cheaper.

I would spray foam insulate all the exterior walls as I bet there is not any insulation in the walls. 

My uncle hasn't had much trouble finding renters in the past.The property has had a ton of rehab over the last year: new double paned windows, new exterior doors, new A/C and heaters, new plumbing (pex) throughout, new tile flooring throughout, some new electrical (all professionally done and inspected), new bathrooms, new fixtures, 4 of the 6 units have new cabinets, new appliances (stove, refrigerator, no dishwasher), shingled roof (less than 5 years old), new trim added to all the units, new paint both inside and out, had foam insulation added to the attic to help with the heating/cooling as well as protect the new plumbing that they decided to run through the attic, 2 new hot water heaters (each service 3 units), No structural or foundation issues, new water line from meter to the building, and not in a floodplainThe lot is quite big (1 acre) and is zoned commercial.

Or is one of them deemed to be the original parcel with full cost basis and the other parcel(s) have zero cost basis?
