That would be a helpful addition to your plan as you would further reduce your cost of living.Also don’t forget from that $600 you are planning on getting in cash flow you have taxes, insurance, maintenance, capex, and vacancy to consider.With two homes, you may want to keep that extra $20k as an emergency fund rather than spending it on a third property and then be left with no emergency funds.

What would be my best route to take if we need additional finances?

All this in addition to 6 other lease violations... 

Your best route might be to buy a 2 to 4 unit property that you can live in and rent out the additional apartments.

Quote from @Lisa Albright: Hi All,Newbie here, just a quick question we are building an addition on our second home, we have a primary residence, and two rental properties.

Additionally, I really want to dive into the property management realm and am passionate about connecting and assisting other Veterans and Active Duty. 

Principal balance currently at 314kProperty Details: It's essentially a "2-in-1" property, with the main unit rented out for $1,900/month and an attached ADU bringing in an additional $1,200/month.

But this comes with pockets of C/D neighborhoods, and higher potential for headaches;  in addition, appreciation in these zips has probably maxed out for a while.

In most single family zoned areas adding a single ADU is not a value add meaning it will not add more value than the hands off cost of the addition.  

Yes, I’ll check with regional building, but curious for additional thoughts here.
