Seeking a conventional mortgage may present challenges for you. Check with your financial institution for more details. Qualification will depend on the amount of income, interest rates, credit score, checking and savings account balances, amount of down payment, amount requesting to borrow, number of years on the job. These are the general items that are taken under consideration. Please see your financial institution for details.
Another option is to check with your city, county or state for housing authority programs that are designed for low to moderate incomes. In my area there newly constructed homes in select neighborhoods that are available under the housing program along with a grant to be applied to down payment or closing costs. These programs have guidelines as well to follow check with your local housing authority for more information.
