Lot improvement in Delaware

[Ryan Van Fleet]

This is going to be a broad question, but I've recently come across a couple of lots that are priced well in a very good area. I want to put together some numbers to see how the deal would work if I picked up the lots, cleared them, and put a modular on them. 

I think my first step is to call a modular company and get a construction estimate and go from there.  I know I need to factor in purchasing, interest from the construction loan, as well as the taxes on the property while the construction is happening. I also need comps for similar homes. I was wondering what else I need to factor into the equation to see if the numbers work.

Also any suggestions on how to take the deal to investors for financing.
