This is a very technical area and the tax issues will depend on your specific situation.  

Financing and tax related issues will force the other into becoming part of whatever you decide to do and you don't want to overcomplicate your marriage with financial decisions that both of you are not on board with wholeheartedly.That being said, there are other ways to invest in real estate that don't involve you moving or evening buying a home.

Issue I am having is that this falls below the 2% although I am able to aquire for less than the max proposed price.Using the 70% rule it works.
