Your problem of no credit is the best pproblem to have and wont take long to fix.
For starters, you should get a secure credit card. Several banks like BOAoffer them. In it you provide the cash that will be your credit; so they do not ruun any risk. Usually is 300 the secret is to use your credit card but never use more that about 35% or 100 and pay it.
That is use up to 100, go to the bank and use the 100 again and pay do not wait for the statement. Once you do this for several months your secure credit card will be change to a regular credit card.
Get two of these cards in different companies. Also get a gas credit card and use it and pay it.
Soon you will have a hiig enough credit to qualify for a loan. I just closed a purchase contract for a frst time buyer who had no credit and doing this he obtain a 690 credit in several months.
Is not about the amount of credit but about how you use it that your credit is assigned.
