We had cash for down payment and went through a broker for our loan who was recommended to us by our agent.

Is it possible for me to get the property listed as a "to be built home" without me having to pull a loan myself to have the property built ?

When I'm done with the rehab, I rent out the property and refinance into a conventional loan.

I know the appeal of the 10% down loan, but recently I have seen some 15% down portfolio investor loans so maybe go that route it should be easier for you. 

This amount is fairly predictable year over year, even with repairs.2) Calculate my loan payoff @ year 10 to find equity at the time of sale.  3) Multiplied this by LTCG of 15%.

After going through the entire process to try and obtain a DSCR loan we were denied at the last minute.   

If you have to, interview a couple until you find one that you "click" with. 2) Let that agent connect you with their network of investor-friendly lenders. 3) Meet with these lenders, have them talk over your finances with you and what loan products you would qualify for at the moment based on your income and assets. 4) Let the outcome of that conversation (#3) dictate your strategy moving forward and take your findings back to the realtor so you can craft a plan. 

I have a few personal conventional loans on some rental properties under my own name.
