Thanks @Kiersten Vance! I don't think I'm fully understanding #2 when you say to refinance with a bank in my own name, etc. Wouldn't my parents need to technically list the place for sale in order for that to happen? Or does it not really matter in the sense that I can take a $395k (portion my parents roughly own) + $30k (remaining of my 25%) loan out, at which point my parents would be paid that amount, and I would then just continue repaying the loan monthly based on that number. Or the $30k I could just pay off now sort of as a "downpayment" and then pay the loan back based on $395k. I'm not sure what type of loan I would need or would qualify for (FHA, Conventional?) in this case. Also, if I do this, would I be able to qualify for the first-time homebuyer credit? Or is that already out the window since my name is on the deed for this place?
As far as the 25% ownership, yes that is technically my portion regardless of the $700 - the $700 was really just an 'arbitrary' amount we agreed to based on what I thought would be enough to get by on at the time (this was determined back in 2007 when my salary was a lot less). Either way, I'll have to crunch some numbers but thanks for the ideas and input!
