The low mortgage rate of 2.5% is a considerable advantage, reducing long-term financial obligations and potentially enhancing profitability through tax benefits and property value appreciation.

Got to agree here, these people usually have a lot of opportunities to make peace with the landlordBut I have to point out, that I have seen a case or two where the landlord was the scum and was just trying to screw a tenant. 

Welcome @Scott Poole.You'll find alot of useful resources(knowledge & ideas) for your REI journeyAll the bestPS: Great analysis of Oklahoma city.if investors first could consider (law, population, job growth etc) that would enhance their returns

It costs a lot, anywhere from $450 to about $700 a year, but I have COMPLETE peace of mind that I will NEVER get that 3 am call for a toilet stopped up (or anything else). 

The thing that gives me peace of mind is going through the loan approval process.

Another option would be to use it to pay off my mortgage, which is a guaranteed return every year (currently at 5.25%), and some peace of mind.

It's also hard to put a price on peace of mind. 

I'm willing to pay for peace of mind to avoid liability as much as possible.Would construction GL cover me for any injuries that happen on site?

I would personally recommend doing it for peace of mind, especially if you are in a Zone 1 or 2 area.

My ultimate goal, once I retire from the Air Force, is to obtain my real estate license in order to enhance my investment opportunities, but right now I am still a novice :) Some of the challenges that I feel I face starting out the gate are finding the RIGHT rehab company if I BRRR and then finding the right team to help with turnovers.
