If the new wholesaler sends me a property with specs (or even seasoned ones) and the numbers are off or does not fit my criteria and needs, I will often provide them feedback of my numbers and criteria in hopes that next time they hit the nail a bit closer on the head.

They were sold to people wanting to build custom homes, and small home builders constructing spec homes.

Even though the inventory is very thin currently, there are always deals out there, they just may not work for the particular strategy / goal you are trying to achieve.In a very hot market like this, you need to have your financing in place and a well defined purchase criteria (property type, age, specs, level of rehab & location). 

What you are asking about is basically building "spec" houses.

Recently I had the following work done at a property:  1) install security screws for existing kitchen faucet 2) adjust deadbolt on a door 3) replace (2) outdoor lights and light bulb (4) replace 3 smoke detector batteries (5) install a spring for screen door (6) install a blind in the living room. 

At what exact moment do you need an architect when building a spec home? 

@Donald S.Make sure there is a good market for a spec in that area.

If I catch the problem right away, I still can call to fix it - I have warranties on most of appliances.I'd say that once a year inspection must be mandatory for PM including pictures.We have inspections from Citi - so I usually go and change filters, batteries, check all electric outlets - anything about safety of the property.

When I learned of the "BRRRR" method from a Denver investor 18 months ago (he wasn't on BP and didn't call it BRRRR) I thought it was genius and began buying rentals, as well as a fix/flip or spec home build each year since.
