Are you looking to stick within your market? 

Plus, you already know the market, which gives you an edge.

In this case, your monthly payment with 20% down will have a good MARKET rate if your DTI works with a much lower month payment and no mortgage insurance(MI).

Plenty of 50-60% leverage loan options for developable land, and may still be more marketable to the LP if you went that route even if it meant incurring some additional finance charges.
