Maybe an investor is flipping a lot of properties and you could offer to pick up and deliver materials to his crews, clean the work sites every night, bring his crew lunch, or whatever.Find a way to make yourself useful to them, and they will reciprocate.

One way that I was able to get into my first property was counting 70% of the rental income of the other unit on a duplex.

As a property management company in Washington, we help owners navigate these challenges and optimize profitability if they want assistance analyzing their property or planning future strategies.

Cash flow is definitely the biggest challenge; both in terms of finding properties to buy that cash flow with a loan on them and just company wide given interest rates and labor/material is up and, at least where I'm at in Jackson County, MO, taxes are way up too. 

Don't forget about listed properties too. 

Quote from @Carson Hyland: Even if you buy the right property, failing to manage it well will kill your cash flow.
