The issue isn't doing the rebates.The issue is in order for the government to back a loan (say FHA/VA/USDA etc) they have lending "guidelines" which say you can only use so much of "Other Peoples Money".

There are many with backing of companies and even governments behind them.

(which makes sense, because that is how it must be done to increase the shingle survival rates).What I'm getting at, is your if you want to be "More Likely" to have "Less Trouble" collecting on a shingle warranty, your installers must follow the shingle manufactures directions to the letter.Shingle Advertising, "What the large print giveth, the small print taketh away".Good Luck!

Background: 22 Years Old, Single- No Kids$30K Annually - Government Employee (Love my Job) Debt = Car Loan totals $6,600K and 2 School Loans that also equal up to $6,000KI'm on track to pay off my car loan on May 17th and be debt free on September 20th as I have been successful in keeping my full time job's pay untouched since mid-January.

If it is being sold or insured by the government, standards are set by them as to what a max DTI ratio is acceptable.The cure is to pay off some of the debt so you don't have the payments to make.

You are fighting with government which can take time.

From there, there are a lot of companies that can help with the printing and mailing.
