Do some a/b testing.

Here's a link to check contractors licenses https://www.cslb.ca.gov/onlineservices/checklicenseII/checkl...If you're going to sell be mindful of AB 968Best of luck

We will upgrade from a C market to an A/B market.  

If you're doing A/B rentals,  does it give you a nicer warm/vibe to have the greige, sure of course.. but if you're doing anything lower than a B rental, it makes so much more sense to do all one color!  

What would be your exit strategy A,B, and C?

You will have to get permits and disclose your contractor ...AB 968 requires the seller of a singlefamily residential property to disclose work done on the property, if the seller obtained title of the property within the previous 18 months.

That being said we have A,B, and C areas.

I typically don’t suggest this, but given your current income I would go after class A/B+ assets with low maintenance and with much greater chances of appreciation potential.

High LTVs, short maturities, mezzanine debt, outside preferred equity, and multiple share classes (the recently popular A/B equity structure) all increase risk. 

Try your dambdest to get a B or higher unit/neighborhood.
