Tankless can be a problem because of their high gas and exhaust requirements.

Since then, I've thought about trying to get three or four large rooms repainted quickly so I can re-rent, and I suspect even a $2900 deposit would quickly exhausted (and that's assuming that there weren't other damages that it was needed for).Maybe, if they really insist, I can require an additional month's deposit... if nothing else, that should get them to drop the subject!

It was completely exhausting.

If you look at the gentrification patterns over the last 20+ years, all other options have been exhausted.

However, it is MUCH cheaper to exhaust your energy efficiency upgrades and THEN size the system to what your building/house/family needs once those are done. 

Are they leaving wet items bunched up on the floor and not turning on the exhaust fan?

Sometimes it's from cooking without using the exhaust fan.

It's irritating and exhausting.

(Houses can be flat exhausting.)I was turned on to Lance by his book on Amazon, "How to Make Big Money in Small Apartments," and how real estate entrepreneurs can get into multifamily with other people's money rather than your own.
