You then have to decide how long it's worth waiting for the remainder.

@Lee Burns  Once you fine tune the numbers and if you decide to proceed, back to your original question, how to fund it? 

Once you have decided to invest, stay close and learn all you can.

That’s what I’d do.Good luck with whatever you decide

Bought a single family home that I was intending to rent out, but have since decided to move into it myself to save myself the commute I currently make from Bloomington.

You also will likely increase the amount of rent you can get if you decide to rent it out and repeat the process. 

This is clearly specific facts and circumstances based but I’m curious to know whether based on historical returns you would have decided on a go vs. no go on a property when you were on the fence due to these variable assumptions such as repairs and capex and your historical experience is tipping toward a lower % than the assumptions being used when analyzing.

I decided that was "highest and best" use. 

If I decided to invest in commercial multi family, what kind of investment I should be looking for 20-25 Units.

Decide how much money you have access to, & the zip codes, city or state you want to focus on.
