Some of the appeal of condo's and HOA's by association is that they don't appear to have been as impacted by the appreciation in Denver.  

Hope and pray or forced.

His business ran into trouble which forced him to file for CH7 (Including the mortgage), which has been discharged, so the note has also been discharged.  

You do the repairs, which forces appreciation, then you do a conventional finance on it to get out of the private money loan.  

I've never dealt with rent control, but I believe that has more to do with the rate of rent increases rather than forcing you to do maintenance/repairs (though there are certain repairs for safety, etc that must be done timely). 

Modified gross lease with base year comparisons will reduce thr impact of increasing costs and pass it to tenants.

If you see vents for a forced air system, those will almost always be separated.

Since you'll be "flipping' your primary, how will that impact your other flip(s)?  

I can't imagine using trailers for clean outs. the guy that died had crap load of playboy mags and air force mags in the attic.  

They are forced to use a third party which is expensive and time-consuming.
