The rate you will be offered depends on a lot of different factors, your credit score is decent so that should not impact the rate negatively. However, the loan amount, type of loan, percentage of the home value or purchase price that you are borrowing, all have an affect on the rate.

For a typical 30 year fixed, borrowing 80%, without paying points, with nothing special effecting the rate, you can expect 6.250 - 6.500%.

Keep in mind that a lender will pull all three credit reports and will use the middle credit score, you didn’t mention if 650 was your middle score or not. Also while I agree that you should not allow a broker or lender to pull your credit report until you’re sure you want to work with them, if they do not pull your credit report multiple times (most only pull it once, then the lender pulls it again just before closing) your credit score will not drop by 100 points, it usually will drop maybe 2-3 points but will not be reported for 30 days. It generally should not be a cause for concern with a mortgage loan (a car loan on the other hand is when multiple reports are pulled and your score can drop quickly).

Right now the chances of you being under 6% are slim to none even with a large down payment. The lowest rate option you have is a 2yr or 3yr arm. With a 650 putting down 20% you would probably fall around 6.5%

That’s a pretty good score. I’d say you would get somewhere around 6.25% depending on the type of loan. Don’t take one companies word for it. Shop around.

Choosing the right mortgage company for your new home loan can sometimes become a stressful process. For many people, a home mortgage will be the most expensive purchase they make but a new home purchase can become one of the best investments you ever make.

Remember that you will be their customer so you must make them compete for your business.

If you put a down payment and depending on your income, I could get you something like 5.75 30yr fixed with no prepay penalty

That is a decent credit score and you should be able to get a decent one of about 6% but you may want to shop around but do NOT let them run your credit! This will bring it down to about 550…. and you will not even get a loan with that. Find someone who will do manual underwriting where they look at you as a person and not a FICO score as well, that should bring it down a bit as well.
