I have never personally assumed a mortgage...but would happily discuss the pro's and con's with you. My direct email is mstock@usavingsbank.com or my office line of 614-339-1206.
As Joe said...why not simply obtain your own mortgage? I would guess that the loan you are considering assuming has a killer interest rate that cannot be matched today?
I can tell you that it is not as simple as you may have been led to believe. You still have to fully qualify for the current mortgage with regard to income, assets and credit, and will of course still have assumption/closing costs to consider.
Let me know how I may help.
Ha, copy that!
