We are hoping to buy a place for her to move into once her lease is up in July.We really like Cornerstone and there is one that is for sale now that we are considering...our Realtor thinks it is overpriced, so if we did make an offer we would come in quite a bit lower than they are asking( they are asking 129,00.00 we might offer 119,000.00 or less.....)My other daughter has a very good deal, living in a 3br/3ba condo at Cornerstone for 290.00 plus utilites( about 50.00) She has 2 roommates who pay the same so the landlord is getting about 870.00 per month for a 3br/3ba.

Since you don't already have a family, could you rent the other two rooms to roommates & get them to pay your mortgage?  

Don't use your student loans to inflate your lifestyle...Continue to live like a college student even after you graduate - have roommates, cook your own meals, buy used reliable stuff only when you really need it.

Mike wants to re-new the lease for one more year, but one of his roommates graduated and is moving out.

Combining incomes in a situation which amounts to little more than room mates will not work.

Existing roommates are far more particular than anyone else would be about screening in a new roomie.

In order to maximize gross rents, we set the price so high that it filters out typical candidates, and pretty much only allows for a house share situation where roommates sign one lease with us, and pay on a per-room basis, but coordinate that amongst themselves. 

I have been living in it and renovating it for over a year now with roommates . 

In such situations you can use a "release of roommate" form.

If you can qualify, there are some homes in the med center that are interesting and you could have roommates to help you pay the rent.
