For the two years prior she worked here as an au pair and after we got married she received her green card and got her first job almost immediately.

It is a long held belief in investing that you  "Marry the property and Date the rate".  

Furthermore, you will already have a cash-flowing property in your hands and you won't have to compete with the crowd of people jumping in to purchase real estate because rates dropped.Another piece of advice you will read from time to time on these forums, "Marry the property and date the rate!"  

Or you can refinance and hold it if you love it as a rental.Also, I'm 41, married with two kids and just bought another live in flip/BRRRR.

I purchased homes when I was married.

If the value has not gone up a lot since purchase, this might not apply to you, but one thing that is often a factor when converting a primary to a rental is losing your section 121 capital gains tax exclusion (up to $250k individual, $500k married couple if you've lived in the property for 2 of the last 5 years).

I'm sure I will not provide the proper information for you all to give me the right advice but this is what I've got:I'm a somewhat recently married 36-year-old dude.

She will be paying rent anyways with me so her paying me rent and building our future wealth when we do get married is a much bigger win than us both paying down someone else's mortgage. 

Since you are likely married filing jointy, you can simply use your EIN from your LLC, which is a passthrough onto your taxes anyways.

Married, both W2 earners at 225k combined.
