I have been burned by this before, I bought a property that was being used as a triplex, and the county zoning had it listed as a triplex for use, when I went to renovate the property the local city government said I had to rehab it to a duplex as that was what their zoning called for.

The aim for this (besides a big fat profit) would be that this would provide far more living units for that property. 

More COs may be required if there are other fuel burning appliances besides one furnace.

I think that this is a point that a lot of investors hit though, where they burn through their dry powder and the next time they get more, they are much more cash strategic about it. 

I am just entering Real Estate because I am burned OUT from my current work!

If guests burn through 500 gallons of water quickly, it doesn't matter because the pump fills it back up overnight.

Quote from @Carol Burns: Anyone here invested in STR's in Blowing Rock NC? 

I'm a little partner adverse in general because I have been burned too many times.

Those were fat years!

Please don't burn me because these are estimated numbers that I came up with with the little knowledge I have now...
