Buying in my name, spouse name - what advantages?

[Damon J.]

If I buy rental 4 properties in just my name, and then later go by buy 4 properties in my spouse's name only.

Will my wife be able to get preferred financing on those 4 rental properties? Will the mortgage company associate the 4 homes I own with herself or will she be viewed as owning 0 rental properties.

We currentlyhave a mortage on our primary home in both names. Is there any way to inexpensively adjust this?

In general is it good strategy to purchase in one name only assuming we both have good credit and income levels?
