what happens if partner refuses to pay his half of the mortgage?
The lender will hold you each responsible for payment in full. That’s the long and the short of it. You both agreed to the loan contract, and if it’s not paid in full there will be all of the consequences: Hits to your credit, notice of default, foreclosure.
This is basically blackmail on the part of your partner, and a disturbing number of partnerships have this phenomenon. The only way I know of to recover the money is through the courts, which takes forever and costs more money. Even when you have a judgment, it can be difficult to actually get the money if they have taken certain steps to place it beyond your reach. Talk to an attorney right now, keep good records, and send everything Certified Mail.
Unfortunately, there are no method except time that I am aware of to repair the damage to your credit once it has been done. You just have to wait it out. For that reason, it is usually cost effective to loan your partner the money, even at zero percent interest.
What if you don’t have the money for both halves of the payment? Well, that’s a real question, and the answer is found in the article What Happens When You Can’t Make Your Real Estate Loan Payment. This is not a good situation to be in. Talk to that attorney about liquidating your investment. It takes time and a lot of money if your partner doesn’t want to.
What can you do to prevent this from happening? Pick a good partner that won’t pull this nonsense. Spend the money to protect yourself up front with a partnership agreement. But the fact is that if your partner wants to be a problem personality, you really can’t stop them in the short term. Not that it makes any difference to your pocketbook, but sometimes it’s not intentional. People do fall on bad times for reasons not under their control.
Corporations are another step people take to protect themselves from this sort of thing, but that brings in all sorts of further problems. How the corporation qualifies for a loan is often a significant problem, and many times practically speaking, is insurmountable.
Borrowing money in partnership with someone else is something to be done with a lot of forethought and preparation, otherwise there’s nothing you can do when bad things happen.
