Hello Cd2enterprises007, there are to many variables to estimate without more detail. The type of roof, pitch, type of garage door, exterior door, foundation, etc. You ultimately will need to get estimates from all the trades involved or consult with a General Contractor.
Are you paying all cash or do you need financing? You can utilize a 203k loan and have assistance from a cost/price coordinator for the project. There are permits required from the city planning department as well.
Your qualifications will be determined by your credit profile, debt to income ratios, fico scores, loan program and how much you want to invest into the down payment and closing costs. Your fico scores can be raised within 3-4 days in most cases to qualify for programs, rates and terms as necessary.
You will need a minimum 580 fico score to qualify. It only takes a few dozen questions to qualify and go over your options. Here are some links to study about me as well as web reference links to many loan programs...
