How much will a no cost loan add to my interest rate

It depends... There are various versions of "No cost". You can eliminate a little, most, or even all of your closing costs by increasing the rate a little, or a lot. Discuss with your local licensed mortgage broker the various options to determine what is the sweet spot for you. With that said, in my humble opinion, where interest rates are today - and if you think you will be in the home more that 4-years, most "no cost" loans are a bad choice. www.MortgagesUnlimited.biz

Need more info like is it a refinance or purchase, what is the loan amount, is a 1,2,3 or 4 unit property, what is the Loan to value, what is your fico, what are the terms - 30yr, 25,yr, 15yr, 10yr etc. of all these the loan amount is the most important because if it is a $50K loan there will be a much larger rate increase than if it is a $417K loan.

Up to 0.5%. If you are going to be in the home less than 5 years, it may be the best option.

It depends, there are many different no cost options. The best thing to do is shop around and get quote from different lenders to see which option will be the cheapest for you.
