Because I want to continue investing, avoiding paying the personal gains is what my mind is occupied with. 

This will minimize the tax burden of the gain you currently have and defers any other gain through the 1031 giving you more buying power going into the future.

I would use the 150K and be a hard money lender for others you would gain the net working with them and the interest you get back put that towards your business for marketing and growth.

You can exclude all appreciation on the original capital gains investment when you exchange or sell a property in an opportunity zone if you held it for more than 10 years.You are able to permanently exclude 10% of deferred gains from capital gains tax as long as you hold the property for at least 5 years and 15% if held for 7 years.Deferral of recognizing capital gains after the sale of a capital asset as long as the capital gains are invested in a QOF within 180 days of the property disposition.

After a little while of this you can slow down and just use the one contractor you have gained a good relationship with and know their numbers on rehabs.

yep your weight in gold.  

They may or may not have good reasons and unless they communicate those reasons and perhaps even substantiate them I really try not to give them any weight.

Check bed frames and chairs for their weight limits. 

POW you maybe just gained a buyer. 

It looks like it could deliver a 7% gain.
