Sorry if these questions seem basic; it just helps to have someone tell me exactly what I need.Thank you!

Basically, I just had to weigh the risks and cut my losses.

We had been including appreciation as a major driving factor.  

I understand (sorta, kinda) the basics of OZ.

Post a new thread here, post on facebook, drive around and call "We buy Houses" signs and ask to be added to their list, post on craigslist, etc. 

I’m not saying it’s a no -go ,but I am saying practice your due diligence and get some professionals involved before you get too jumpy  if those numbers are correct that's about as good as it gets spread wise in the Portland market.. 230k ARV is one of the very cheapest areas of the city if its a free standing SFR detached.. and you say its on septic that leads me to believe its not in the city.. and seller warranting that stuff is worthless.. just try to collect after the fact when he is long gone with your money.. get a good contractor in there to assess the condition and what it will take to rehab.. 30 to 40k in our market is basically cosmetic only.

. - 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? 

From 2002 to 2016 it is basically littered with the same thing foreclosures and collections including the state of Kansas.

Drive the neighborhoods in your market where flips are happening. 

The fact they are complaining online might be an indication the property manager dealt with them properly so be sure to ask the manager for their side of the story.I hope this basic guide helps.
