Would that still deter you from accepting an offer?

I would not ask the question nor would I accept a tenant that I have not approved through my normal tenant recruitment and screening process.

In a few years, you can take the broker's license test(s) and then open your own property management business.

But I think they will likely accept based on rents in the area, cost of moving, etc.

I would first test him out on a project before JV'ing.

With this approach you have to accept that a certain number of unwanted sales pitches,  bots, etc. are coming your way.

The fastest we can move a SEC 8 tenant in from the time we accept them is 20 days.

If I was you I'd skip the realtor all together and look for off market properties because if you're looking for investing deals, you'll have to go through a LOT of MLS deals and a lot of offers before you get one accepted.

you need to decide if you are willing to accept this. 

There are no major work currently, but what are the regular maintenance and cost of the well/septic, such as inspection, cleaning, testing, etc?
