After all, even $150 savings per month is equivalent to the cash flow from a single rental unit.One thought that crosses my mind is that I probably wouldn't make insurance claims on small things like appliance replacements, since it will increase the policy premium(?) 

I think typically they want to see some revenue coming in and it needs to be an established company.Regardless I think your mind is in the right spot. 

But so have my property taxes and insurance, so keep that in mind.  I

You mentioned that in our phone chat but it kinda slipped my mind. I

@Matt Todd wow that was a mouth full, I had no idea about the 3 tenant max that's very interesting I'll have to keep that in mind, I would already be worried about younger adults leaving every summer if it was Orem or provo college tenants.

With this in mind, I am thinking that the less-than-stellar cash on cash ROI might not be as important as long term benefits.And would a bigger down payment be advantageous or a detriment, since the lower monthly mortgage payment would come at the cost of tying up capital that could be invested elsewhere?

It will be changing soon but I have all class D units and none of that applies in my mind. I

With that in mind, I would not necessarily need an agent to represent me at a wholesale transaction right? 

@Tommy Brown, that's a good point that you made and that has not crossed my mind. I

It utilizes a formula to calculate the return on investment by taking the property’s annual net cash flow and divide by the investment’s down payment, and is expressed as a percentage.One important detail to keep in mind is that Cash-on-Cash Return doesn’t include the property’s appreciation or any principal debt payments.
