My personal goal is to build a rental protfolio, but I'm open to anything.Thanks in advance. 

So, your focus may need to pivot from high rental cash flow to little to no cash flow as a rental with an appreciation upside.I would recommend taking your $150K to $200K and securing a solid equity position in something that will cover its expenses and maybe provide a small cash flow, but then is poised to appreciate nicely over the course of the next several years. 

@Christopher HeidrichRecommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

Purchase price: $178,000 Cash invested: $10,000 primary home own use has an Airbnb/ short term rental 5 months out the year/sometime this year will try BRRRR

I do a combo of short-, mid-, and long term rentals on the northside of Chicago and surround suburbs.

Fast Turnaround: Unlike long-term rentals, you can cash out quickly and reinvest.

They’ll have a deep understanding of the market and a strong network, which can help you identify the best opportunities.Owning rental property isn’t as simple as it might seem.

If your goal is to have a cash flowing portfolio of rentals. 

Do you currently own any S8 rentals in Evansville or another market near STL?

That being said, 70k is flip money or buying a rental, not land money, I don't know of any development that can be done with only 70 grand but I could be wrong.
