That would be by far the absolutely lowest rate in the entire country....which is why it's setting off alarms for me. 

and its the absolute truth.. it goes like this from my experiencecommercial broker gets a deal from seller. 

I would guess my home would appraise at $220K at the absolute lowest but probably about $230K maybe 240K. 

So if all goes as planned I'll be keeping my cash-flowing tri-plex and adding a 300-unit storage facility all from my original $42K down payment.Of course I'll be making a higher monthly payment now that my mortgage on the tri-plex has doubled but the storage facility cash-flow can absolutely cover that and a lot more.  

Or do you use an absolute number for yourself e.g. % return?

@Moses Mesa Absolutely would not go there.

I don't really have a lot of income as of right now, although I am willing and am currently practicing not spending any money on anything that isn't absolutely necessary, it will probably take me some time to save up a substantial amount.

Keith Knobloch is absolutely correct.

I'd need to BRRR and pull everything out plus some...meaning I'd have a great ROI because I'd have nothing invested...On the other hand, if a SFR yielded 1300/mo cashflow, I might be happy with as low as a 10% ROI because of the absolute dollar amount returned for my amount of effort.Where you fall on this spectrum also depends largely on how much capitol you have to work with and where you are in life with respect to your goals. 

You will absolutely get sued with a pool on the property.
