First time Multi Unit Investor with specific targets

[Arnuv H.]

Hi all, hope this finds you well. In need to generate $3k+/month net positive cash flow and willing to invest upto $600k in multi unit properties. 

I have one SF in Cali that i manage myself however thinking of going out of state.

Not worried about appreciation as long the target is met. So far based on my research Michigan and Ohio are top of the list, would love to hear suggestions about any other location that can help me reach my target number. I worry about maintenance cost of the Multi units in these locations as they are 100+ yrs old.

If you have any suggestions on locations to consider, strategies or even have any good realtor/contractor in the area to share would be super grateful.
