. - I decided I didn't want to mess with it because Im starting another project with higher potential return.Now, as an example, I look at this one:https://www.zillow.com/homes/63-GRANVUE-DRIVE-BELL...Its on the Auction block, if I picked it up for 2 or 3k, and sold it for 10k to someone else who wants to work with it, essentially a wholesale deal, and didn't spend any money fixing it up, and agreed to max 1k realtor fees if any, I might make some money on it.If you go to our county tax assessor site, and search '63 Granvue', youll see that 1) the total taxes for 2018 are $2981.38, and 2) they are paid by the bank already for 2018 http://www.co.st-clair.il.us/Pages/parcel.aspxWhat I am asking is - if I bought this at auction, and sold it within a couple of months as a property someone else can rehab, how would the property taxes work / what would I end up paying? 

Drive the neighborhoods in your market where flips are happening. 

As Wayne points out, there are two factors to consider, that often times are mingled together.

Driving into this website, I saw, what I thought, was an abandoned 8 unit apartment complex close to my area; (close to Birmingham, Alabama; specifically Jasper, Alabama)I drove to the site and discovered that every unit was occupied.

In my market (Columbus, OH) a SF next door to a duplex unit isn't going to rent for dramatically more in most areas, assuming similar factors of condition, sq ft, etc..

We live in a society that you can earn money anyway you can think (driving a car, delivering food, charging a scooter overnight).

Now they all have cars but the problem is many do not drive 😀.  

And even further, the minimum cash down is about 25% although I'm looking to put down more to drive up the monthly cash flow.On your other calculations, the current management company I use to manage my portfolio takes 10% of the monthly gross cash flow (and they are really good at what they do so I'm I love the no headaches).

Too many fish in the pond driving the prices up with people willing to buy places at a 4 or 5 cap.

This investment didn’t meet all the criteria as a flip as appreciation was a huge factor.
