If there's a rental market, that may be a fairly stable income source while you wait for something else to develop.5000 cars per day wouldn't be enough for a fast food restaurant or something like that but would maybe work for a Dollar General or similar.The offer on the 10 acres is for farming purposes?

Alternatively, you could go into a more stable C class and move closer to $150/month net cash flow (after vacancy, maintenance, property management and of course your debt service/taxes/insurance.) 

Or should I wait and build up cash to secure stable, long-term financing and hope I’m prepared when they are ready to sell?

@Douglas Gratz you talked about shifting your perspective on class A so one thought experiment is the following:I want to have some stable and liquid assets with low risk and a good return?

We're a stable market that holds value through the downturns, rent rates in b and c class areas hold steady as well.

You are correct the price of entry is more expensive than many other markets but the front range market is pretty stable and there is a high demand for single-family rental properties. 

However, some investors are comfortable with that as they're looking for stable, good quality rents in good neighborhoods and a good chance at appreciation.

It’s more stable for the neighborhood and less likely to get neighbor complaints.

I am stuck with either pursing Construction/Project Manager or Property Manager as a stable income career for years to come.

We are looking to transition from living in 8-11 different homes we pay to rent, to owning 3-5 stable places we can return to every year and that we can STR while we are not there.
