By calculating their debt-to-income ratio and factoring in a down payment, buyers should have a good idea of what they can afford to invest, both upfront and on a monthly basis, when it comes to their home.
Though there's not a fixed debt-to-income ratio that lenders require, the old standard dictates that no more than 28 percent of your gross monthly income be devoted to housing costs, called the front-end ratio.
Including all debts with housing costs is the back-end ratio, and lenders prefer it to be under 41 percent.
"I really ask buyers to qualify themselves because although we can use that 28/41 ratio as a guideline, each of us knows our finances best. If we're used to paying $800 in rent but 28 percent of your income would be $2,000 then maybe 28 percent is too high," says Winesburg.
"Find out what you can afford and then you can back into everything else. We know the money you have available to put down, we know the monthly payment and we can solve for the third variable -- and that is the home price," he says.
Figure out your down payment
Scraping up that initial down payment takes some effort. Though FHA loans require a less substantial down payment than conventional loans, it can still be a huge chunk of money for a young person or couple.
Uncle Sam is here to help, however, with the first-time homebuyer tax credit, at least until the end of April.
Some borrowers working with a state housing finance agency can use the tax credit for a down payment. However, not all state agencies are offering interest-free or low interest loans to be paid back with the tax credit funds.
Other programs can assist buyers with qualifying incomes and situations.
"I've helped arrange assistance loans for $10,000 which are interest and payment free, and forgivable after five years. Although considered a loan, they're more like grants. Other programs can provide up to $40,000 interest free," says Winesburg.
"Each state is different, but most of this money comes from the HOME Investment Partnership Program, which is a federal block grant to create affordable housing," he says.
Finally, speak with mortgage lenders when you're starting the process. Check with friends, co-workers and neighbors to find out which lenders they enjoyed working with and ask them questions about the process and what other steps first-time homebuyers should take.
