It is important to be realistic about your budget when financing. One of the most difficult lessons learned from the housing crash is the importance of purchasing a home with reasonable mortgage payments. To determine your monthly mortgage payment, estimated closing expenses, as well as other factors that can impact your purchase, you can use an online mortgage calculator.
Although window-shopping is acceptable, you should ensure that financing is secured in a timely fashion. The worst-case scenario is for buyers to find the house that they desire only to lose it because their loan application hasn't been approved.
With information about HUD resources, approach mortgage lenders. There are two options available: The $100 down payment program and the 203K rehabilitation and renovation loan. This loan is specifically designed for financing renovations needed at the time you purchase the property.
