My advice:
Don't do it. The first rule in real estate is location, location, location. If you buy in a 'war zone' your property will NEVER appreciate. It really comes down to how much effort do YOU want to put into your real estate holdings.
I have SFRs in good neighborhoods with good schools, etc. At the present time I have 9. It takes me about 20 minutes a month to send out all the chase quikpays and do bookkeeping. My tenants call a home warranty company for fixes, pay the first $75, and these properties basically 'self run'.
A good friend of mine and I JV on a 4 plex a few years ago. In contrast, we had someone break into the washers and dryers on numerous occasions, a drug dealer, a pot smoker, a gal who had boa constrictors, and more issues in a month than my 9 SFRs had in a YEAR. A reality show would have had less drama.
We eventually sold after a year at a very slim profit, AFTER putting in 40k of improvements (new h2o heater, AC units, roof, etc). It was literally putting lipstick on the pig and hoping someone would buy it.
Unfortunately you get what you pay for. You have to decide if YOUR time is worth that type of effort for that type of money.
In contrast, my former partner LIVES off this type of 'chaos'. He has 24 doors presently that average about $200-$250 a door positive cash flow, based on 100% occupancy. But he is HOPPING all the time and this IS his job. He doesn't buy for appreciation, but cash flow only. His ROIs, especially compared to mine, are 'killer'. But there is obviously a price to pay.
Since I still have a good career, his 'model' is not an option for me.
