As in you want to contract it out yourself (not hire a builder); or as in you own the land and are going to hire a builder to construct on your property?
You will need to find a place to loan you 80% of the value of the land and the rest you will have to self finance, once it's done get a Home Equity Loan to payoff the loan on the land, and credit cards/personal loans used to build it.
Yes but I bet the fees for both loans would be less than one conventional mortgage
I'd call Brenham National Bank for the loan on the lot if you go that route, maybe someone else has a better idea, the main problem is that "you" are the builder.
There are limits on taking cash out of a lot under 200 acres I believe so that may not be an option. Our bank finances a lot of new construction but like most lenders we won't touch owner/builder stuff. There are lenders out there who will, however, they charge rates almost as high as hard money lenders.
