Adding my name to the deed?

[Jeff Wood]

I am looking to purchase my first investment property but have a question regarding my primary residence. When we bought our house a few years back my name was not added to the deed (long story) Is it better for us to add my name to the title / deed for investing purposes or should I keep my name off?

Does it matter either way? 

Will that help / hurt a mortgage rate?

Any input would be appreciated.
