To get the base info, use the calculators on my website, click on "figuring out the money" page.

Alot of factors will vary the interest rate such as your credit....be more concerned with YOUR credit score...is it above 680? OK is above 680, then 680 to 700, and excellent over 700. Before you go looking for a loan or a house, know your credit score.

Unless you plan on putting down 20% or more, do not expect to get the interest rates you see on TV.

The typical interest rate for a person with decent credit, (score around 700) on a single family home with 25% down could be around 5.75 to 6.25 % with no points and no origination. When you use the calculator on my website, put these numbers in to give you an idea of what the monthly payments would be...so at least you understand how the numbers will vary.

Email if you have more questions.

Depends on your credit score and the loan program. You could get away with 0 down and if you got the average interest rate of say 6.25% the payment would be 240.11. But again this depends on how long you finance ( i used 30 years)
