There is also a one-way air vent that can be used for any plumbing fixture not close to a wall for venting.

The question now is can we control how fast will the air rush out of the bubble :-O

My husband was Air Force almost 8 years."

However, the wall furnaces that I have been looking at are only rated at around 75% efficient compared to the regular central air units that are around 95.5% efficient.Any suggestions on heating a 800 square ft apartment without duct work using natural gas efficiently?

I've preferred a small air sprayer over a Ryobi quart airless, but the compressor for it is not portable.

The San Diego market is not the Steamboat Springs, Colorado market.Rank top 3 for anything meaningful, above Zillow/Trulia/etc and above the other real estate agents/agencies that have been doing this for 10 years?

I will say 2015 to present was a great time to make a mistake like this as we have seen appreciation which thankfully has acted as cover up to our blemish (if we are able to sell it in the spring without a big dip in the market).All that being said, a flood policy can eat all gains. 

My market interest is creating monthly cash flow through rental income in Colorado Springs/Manitou or even Pueblo, CO.

We didn't chose to do a 1-year lease with our tenants for the first lease because they were moving in in the fall and if they chose to move out at the end of the lease term, we wanted it to be during the time when it was easy to find other renters (for our market, that's the spring).
