@Michael Bishay your biggest challenge will be getting your expected ROI out of Class C & D properties.S8 vouchers aren't necessarily a guaranteed solution. 

@Joshua Smith - The biggest lessoned I learned is, it's expensive to own real estate.

Selfishly started looking for flips or BRRRR projects where we can use these incentive to our advantage and found out there are many investors already doing that.

Yeah the IL property taxes are one of the biggest downsides of buying in Illinois.

I thought about offering a credit towards the utilities and having the tenant cover whatever the remaining monthly utility bill would be as an incentive to hopefully rent this property faster, any thoughts or recommendations on this?

Last month was my biggest month so far.

I realized that builder gave many more incentives when I paid cash vs when I used an outside lender (builder’s price with their lender was much higher).

Or, it may be in parks I usually don't do business in and move them to other parks I do business in that give me incentives (i.e. pay for moving costs, hookups, free lot rent, etc). 

Financing and loan terms can be a critical component to supporting cash flow or incentive on multi unit or commercial properties..

I have looked into investing in Maine and the biggest challenge I found was many properties did not have tenants paying for utilities.
