It seems most of the bigger roofing companies make all their money on insurance jobs charging $400-$500 a square which would be ridiculous for an investor to pay. 

One thing I'm struck by is no DST company so far has been able to provide their track record.

If your CPA firm is not experienced in them, I would look for a company that specializes in 1031.

If we built one of these spec homes (owned as our company), and then did a 1031 exchange under our personal names, is that viable because the parties are two separate tax entities?

We did not use a realtor in this case and had a title company act as the intermediary.

you can consider a sale pitch.. but just remember one usually has better advertising through the MLS, also better access/availability unless you have time to field all the phone calls and arrange showings.  

The city has an annual output of $132 billion and a heavy concentration of Fortune 500 companies, making it a top economic metro.

Our company, 1031X, is 30 years old and is qualified to execute 1031 exchanges in all 50 states.

:)Are you familiar with this company?

It may sound nice to pay a 6% management fee but the extra fees can add up to be more than the other company that charges 10% with no additional fees.
