We built our house also. We spent a year and a half lookng for the land. Then another year getting the design ironed out, and the quotes needed for the construction loan. We worked with a local bank that specializes in owner-builder projects. Our construction loan was set up so that when we were finished it converted automatically into the permanent mortgage without incurring additional loan fees.
You will have to show all the detail to substaniatewhat you are going to build as they will appraise the loan based on the details of your package. The bank used a voucher system that you paid the vendors and subs with. That way the bank made sure they signed off lien releases to get their payments, so when you are done, you do not have any vendors or subs trying to get more money or make claims against you. For the vendors that didn't want to use the voucher, we used a visa and took a draws to pay it off each month. Just had to show the bank what materials charge was for. You will have to be absolutely anal about your record keeping as it will be your best friend to keep things straight.
I won't lie, it was hard work. But, as said above, it was very rewarding and we traded our labor for top of the line materials. How much you can do will depend on your skills. The only subs I hired were the septic system installer, the plumber, the flat concrete work and a taper for the drywall.
Some of the things we did, were run all the heavy equipment for clearing the land, the foundation (165 LF of 8" wide x 10' high), raised a timber frame, installed stress skin panels, tongue and groove pine on the ceilings, electrical, fire sprinkler system, radiant floor heating system, tiling, granite countertops (cut from slabs to size), site build all cabinets, hardwood floors, exterior siding, hang the sheet rock, installed all the appliances...you get the idea, just about everything.
It is one of the most rewarding things I have ever done. We started raising the frame Memorial Day 2004 and moved in May 1st, 2005. We did live on site in a 5th wheel because our other home sold very fast. I worked 4 tens so I had 3 days over the weekend to to work on it, plus evenings the rest of the week. I had family and friends help raise the frame, and my brother help with the foundation.
I'll get some pictures of the various stages when I can. I still have some small amounts of trim work to finish.
The biggest pain in the ass was dealing with the county to get all the permits issued. You would think for the $28,000 we spent on permits, you could get some kind of service instead of being jerked around all the way through it.
I would build another house again, just not in this county.
