i just saw a house that i liked a lot. It's 525,000. I already have a house that I'm still paying on. According to Zillow, it's worth 452,000. I got it last year for 253.Now, here are the questions. I have a 30 year fixed loan at 3.25% .Is there any way to sell my house,put 150 on the other house and still keep this apr and maybe modify the present loan? It's a V.A. loan. Also, I know this is gonna cost thousands from realtor commissions,and all those other charges that go with buying and selling. Is there any tips or good advice to save money doing a transaction like this? I'm hoping if it would go through,that the monthly increase will only be 1 or 2 hundred.
