Buying a property and selling the back lot

[Jared Wagnon]

I'm looking at a property with a small 3/1 888sf home on 10000 sf lot and I'm wanting to sell the empty 5000sf back lot. It has access to the next street over. I'm hoping i can recoup my out of pocket and have the front lot with the house for basically nothing. My question is what does that do to the value of the property I keep? I'm sure the value would decrease but I'm still paying that bigger mortgage.

Just getting started here...

Thanks!
