I hope that makes sense how I am describing it.

That is fantastic by all accounts, but you are describing a job, not an investment.

This is because in addition to the maximum 20% profit sharing contribution Steve described above, the Solo 401(k) also allows you as the employee to contribute $18,500... or $24,500 if age 50+.The employee contribution may be done on a Roth basis with no income phase-out, which is an exceedingly powerful wealth building strategy.And, with a self-directed version of a Solo 401(k), you can then take that tax-sheltered retirement savings and invest in what you know... real estate.A financial advisor that is not 100% focused on conventional market based (commission-able) investments, but who also understands the power of alternative assets and planning in a broadly diversified sense will have much greater traction with the realtor niche.  

Describing his duties and his form of payment.

So you would have to buy two of the remaining units to get over 60%.From what you describe unless you are in a high demand location the size/condition of those other units suggest you might be able to make a fair market offer that might not break the bank  (knowing nothing about your own finances of course) especially since the housing market has slowed down a bit right now in seattle,  though of course some areas and segments are more affected than others.How much do you know about the other owners?   

Sounds like he is kind of financially strained the way you described the situation.

If you start buying and stay in the market like @Christian Montalvo describes, then you will start to find the "unicorns" that are good appreciation and good cashflow.

I am hearing lots of people who are self described professionals in the business saying that current owner searches are enough.

Not applicable in the situation you described.

There is one company called Nordic that has something like you describe I think in Pattaya, Phuket, and Koh Samui.
