@Kris TohovitisI wouldn't recommend using your cash to pay off the mortgage on your primary residence since you can likely get a better return on that money by investing it.What's your buying criteria for the multi-family property?

I don't know your living situation but if your paying x,xxx for rent or a mortgage and instead by living in one side and renting out the other you will be paying y,yyy instead and y is less then x that's great, especially if you can rent out your primary residence and make income there too. 

@Steven Hamilton II I want to mention that My husband and I both reside in California, and I manage the property remotely from California via Zoom calls, and also physically visits the property.

They'll request proof of income, proof of residency, and non-payment notice. 

I personally use the mass text capabilities through my Resident RE CRM.However I have a few friends who wholesale and invest and use Mobile Monkey to mass text and from what they say the price is pretty reasonable.

I can or have already looked up citizenship, residency, taxation, crime, inflation, etc.  

I just completed an exchange of a single family residence in Scottsdale to a single family residence in Durango, Colorado. 

Investment Info:Single-family residence wholesale investment.

Again, to reiterate, the risk is less burdened because the property also serves as your primary residence.

Investment Info:Single-family residence buy & hold investment.
