Wait I bet you will tell them..

It is a safe bet to say between $100-$200 monthly.

I want to include in my spreadsheet 3 columns for low end, mid grade and high end upgrades as well.

Identified 36 specific cases on the Prel Rep that I wanted to further review (Had $$ in the Estimated Value of Estate column).2.

Bet you can't guess where.

I bet $1 wouldn't be seen as enough or 'reasonable' consideration for the transaction.  

In DFW w values rising quickly and having made renovations, I bet you can pull that off.

With online banking today, a defacto budget can be seen by, downloading all transaction from the first of the month to the last day of the month, eg Jan-1 thru Jan-31 in CVS format.double-click on the file and you get a spreadsheet.annotate each line by the kind of expenditure it is: {cash, food, utils, car, internet, entertainment,...}select the column with your annotations and sort ascending, extend the selection.If you know Excel, insert a line between the groupings, and SUM() the values of each groupwhoola! 

You best bet is to go to your local Real Estate Investor Associations and find some lenders there.

Your best bet would be to find an experienced builder in the area that is familiar with the process of building in the area and talk to them about what it would take to design and build a home there.
