The first key to finding a list of homes that matches your requirements is knowing your price limit. This can be done by getting a pre-approval with a lender. The lender will assess your income, credit and other aspects that define the amount you are approved to spend if you are getting a loan. When all of that is done, you would then contact your Realtor and tell them that you would like to see a list of homes, in your price range.
Now if you are looking in terms of renting for a lower income home you should check with your local department of health and human services and talk to the appropriate person for low income housing.
I hope this helps you.
