The point was how low of a CAP rate would be needed to achieve that goal based on the starting point of available funds.  

They want a two year lease, no last month's rent, and a discount off the premium price I probably could achieve with more time on market. 

It just depends on where you are looking and what returns you are trying to achieve. 

I have visions to achieve .

I.e. the smaller the space the high price per square foot you can achieve (and thus increase the buildings return).

I've seen this happen first hand and it didn't end well for the owner of the park.  

I wish you all the best of luck and am excited to see you achieve your goal by 40.

I've learned here that developing better systems, delegation of work/ responsibilities and building a team is the only way to maintain or increase project flow with the goal of achieving a better quality of life.  

For AC, you need separate ductwork for supplies and returns between the units, separate blowers, and you also need separate cooling systems - condenser and coiling coil; you might be able to use mini-split units to achieve that.For hot water, you need the piping separate for the hot water, and then you will need multiple water heat sources with one per unit.

I wish the best of luck to you and hope you achieve what you're looking for!
