I'm looking to get back into the buy and hold for cash flow game in multiple out of state locations.

We're projecting around 100-125% to them including annual cash flow and a capital gain at sale in 5 years.  

Finding a good renter who likes condo living seems like a relatively safe bet...if the positive cash flow is not eaten away by capital expenditures, lack of reserves, and routine maintenance on big ticket items.  

At least PTs and OTs will still have a steady flow, but there are talks of  7 day plan of care.

I'm looking to invest in properties to build long-term wealth and eventually provide cash flow for retirement in 10 years.      

I'm interested in buying and holding rental properties for long term cash flows, House Hacking the next property I live in, and possibly wholesaling to build investment capital quicker. 

It should help you build cash faster and if you buy it right a 4 should cash flow better than a 2.

If a new tenant comes in every 18 months, that eats away on a few months of cash flow...Is they typical?

There are several other strategies you may consider (BRRRR, subdivision etc.) but acquiring a simple cash flow property in Tacoma can be a good first step.

If an agent specializes in real estate investing, they should thoroughly vet each property they present to you ensuring that it will show positive cash flow in the current and projected conditions.
