Fastest growing company 3 years in a row now - blows away the school of hard knocks.

These "hipsters" are young college grads who will live in areas that are (A) relatively inexpensive, (B) low or trending down in crime, (C) close to attractive civic amenities, and (D) are close enough to jobs. 

That blows for owning a house 20 years.If you sold and bought the two other houses instead and they doubled in 20 years, you'd have two houses close to being paid (you'd still owe about 65k each) off that would be worth 800k total.   

Sometimes it will seem great, but then it gets it horribly wrong with confidence.While most exchanges are relatively vanilla, using an experienced QI and tax advisors in the process is well worth the avoidance of blowing up a 1031. 

Saw it go great, and I saw it blow up too.There's lots of moving parts to buying an asset, fixing it up, and selling it for profit. 

With the roof the other issue you have to consider is blow off.

Just click through the active listings and see how long they have been on the market, if they are mostly longer than yours, at least yours hasn't gone blow average yet.

And lets in all the humidity that was removed during the day.I once considered adding a duct and fan to blow air from the basement to the 2nd floor in summer, and from the 2nd floor to the basement in winter.

Wait til something blows up and they get in court on just about any issue and learn what they thought they were was not at all what they were....LOL

For example I'm thinking of David Greene's suggestion that you agree up front to provide a monetary incentive for the GC to get the work done correctly and on time, along with a penalty for blowing past the deadline.
