Can a husband and wife have their own home loans out at once?

[Valerie King]

My boyfriend and I both still live at home with our families. Our plan is to each take out our own loans on multifamily homes, which we will house hack. So he will have his and I will have mine for at least a year to satisfy the occupancy requirements. That way we'll benefit from the perks of homeowner loans on our first homes/investments as opposed to buying a single family home together first and then having to invest in buy and holds the investor way and put more money down/have a harder time getting approved.

The question is: Can/should we make these purchases and take out these loans in our own separate names before we get married, or can it be done after we get married as well? 

If it can be done after we get married, one of us might buy a multifamily in one of our names pre-marriage. Then once a year has gone by, we would probably get married, look for the second property, and move into it together, with the other one of us taking out the homeowner loan on it.
