I will take the negative too and glean from it. there is no magic formula for this... get a job in the industry earn and learn.. save and then invest.. no ability to borrow basically and no cash will be big time waster for you.. don't waste time on something that is a unicorn and not real. 

His wife has a good job, so I am confident in his ability to pay the money back even if something bad happens to the house.

The deals made are technically deals of and for the growth of the Solo 401k.

I do agree w/ @Aman S. on variables to consider and believe that metering of units is a big factor in pricing becuase of the ability to minimize variability in your expenses. 

Also choosing a good market with JOBS, population growth, and demand for rental units.

Please note, I don't need money at the moment and don't have any other investment vehicles that will generate a guaranteed 8-10% growth to my investment.

No matter what happens to the value it's going to cost you a lot to hold plus any repairs.If the price goes up 200k who cares about the holding cost.If the price goes down 200k because we are at the top of another bubble you will either have to keep paying for a long time or take a huge loss.I hope and feel like the current price increases we are seeing are natural growth.

@Sherry Addy Millington is seeing a lot of growth!

Look for long term growth in jobs and population.

There isn't a 30 yr period of less than 11% growth throughout its history.
