stan_the_man, thanks for replying. Really appreciate it.

So looks like my spouse's credit will be fine in a few months. So for me, I only have auto loan which will last for another 3 years and I use 2 of my credit cards very actively. 

Basically, the difference in closing cost will be about $1500 more (not due to credit scores), if my name is to be added to the mortgage.  I am just trying to weigh the factors here and decide if it is worth paying 1500 more in closing right now and keep mortgage on my credit (or)

not pay 1500 more hoping that I am not losing out on building my credit ???

Any further comments/suggestions?

Thanks,

T
