This is little area on right size of Edenvale and 101.

Staff-size?

That is the size claim where I would want one involved if it were me.

I am exploring the option of selling a portion of my ownership to a co-owner (around 20-30%).

I think mid-sized GCs would be more interested in this type of thing.

I am seeing a ton of investors spending money on education to get into bigger deals at an accelerated rate only to retreat back to buying the properties  that were of appropriate size and undertaking.

Does anyone have experience or advice on how to choose the right size?"
