Or you can sell it, split the equity, and go separate ways.I'm not a fan of borrowing from family/friends unless all parties are honest and everything is documented in a written contract.

From 2nd Mortgages to 1st MortgagesWhen I started, PPR was buying primarily 2nd mortgages. 2nd mortgages is essentially loss mitigation (helping the borrower get back on track and stay in their home).

Most are for the borrowers and not the lenders - so they want them to be very simplistic.

I would stop short of saying I found the inflection point of optimality and being pragmatic. 

Then later as you grow older and no longer want to share your space you can just stop renting the other bedroom.

So if for example, a max LTV for a borrower's credit score is 75%, the program will reduce to 70%.

This stops you from over paying and renovating beyond the neighborhood. 

Turn the water heater valve off and see if that stops the pressure loss. 

I borrowed the $25k down payment from my parents at 8% and got the deal done.

You'll probably need a co-borrower and someone to gift the down payment.There's a Conventional loan (FNMA family opportunity loan) that allows your parents to purchase a home for you (and potentially roommates) to rent while you're still in college.
