I did not expect such a custom and valuable answer that fast.

@Dave Foster It was our primary, then moved to rental for last 2 years..thus fitting into both the 121 and 1031 options, no?

There is a significant difference in rehab costs between those generations: anything pre-WW2 was custom built on site.

Quote from  Foster: @Anthony Quint, the 1031 exchange is something you don't have in CA that allows you to sell appreciated real estate in the US and purchase new real estate while indefinitely deferring paying tax on profits.The thing about this for a non US citizen is that you will be subject to a 15% withholding called the FIRPTA withholding tax. 

Hello all, I am trying to figure out if this custom home on the hill in Castle Rock Co is a good investment. 

Unless you are terribly priced, or have a severely limited customer pool, turning people down is going to be part of the business. 

But higher rent per door for larger doos, with same number of calls/customer care (usually). 

Our world changes rapidly and the way to reach new customers and engage current clients is always changing.

They are transitioning from the custom home model to a spec home subdivision model.

Depending on the demographics of the area, I've found that Home Depot/Lowes is fine for just about anything going in a regular rental.One must consider return on investment and buying fancy custom cabinets won't yield much if any more rent that box store shaker cabinets, especially in a duplex.Get some decent cabinets and a good countertop and you should be good to go.
