These sites have very generic and do not take into consideration things like, building codes, zoning requirements, light and air requirements, site orientation, utilities, soil capacity for foundation types, etc.

The problem is steam pushes out the air through the radiator vents and vents on the mains.

That's also why I put air quotes around "hidden" because if you actually look at the leases this can be missed.

Best of luck in your market.I'm sure you'll get some stories...lots of "hot air" around here ;) Just remember that investing is relative to your individual goals, needs, skills, abilities, and resources...just because it worked for someone else doesn't mean it's a good idea.

We hired an "environmental hygenist" to test the mold and air to determine what the mold was and how significant. 

I have had them create listings out of thin air - listings that simply never existed, and I have seen WILDLY inaccurate Zestimates. 

Should I accept Online payments through Cozy or something like that.

I’ve heard of wall A/C units as well as air handlers... however, I don’t have experience with either.

I'm personally using a program called Air GMS but they focus more on Air BNB.I love the feed back so far from everyone.

Which is great for Air BNB.
