@Franklin FletcherThat's a great return!

I think a return on invested equity analysis outlining a few scenarios with my models would answer your questions. 

.- Stock market opportunity cost: If the brokerage account has strong holdings, consider if the return potential justifies cashing out now.Given the current market dynamics and your goals, reallocating your brokerage funds into a multifamily property in Rochester could provide substantial benefits.

If you want some very broad strokes that are asset class specific, but not location specific.Highest risk and return to lowest risk and return, offices is at the top.

Your rate of return was 13% versus the 9% return not utilizing leverage.  

You will want enough return for the deal to support itself or you won't be able to scale well.

. - Catching up on your post a little bit late, but better than never!

I usually look for 10% return if not more. 

The TIME for 100% return of capital outlay shortens. 

It will be too late after you sell.
