Although it will definitely be harder to make a decision on a house (if the pictures are non-existent of sub-par quality), you can still run a lot of the numbers or get someone to do it for you. 

It all depends on high end vs low end quality and location.  

However, one of the tasks that he gave me was to write down a list of cash investors that I have rounded up over the course of the weeks and send them to him for quality.

When you hire good contractors and tradesmen, you are paying for quality and speed (keyword: good!).  

Sell it because no one else can find the same house for the same quality at this price.

Screen your tenants, treat them like human beings, and see what works for you.

Yes, they could always sell it to someone else, but they have to convince someone to buy it and there's no guarantees if it's poor quality, so again there is an extra incentive to put in extra level of due diligence care.B) Your money starts earning right away.

You can touch menu at the top of the screen in the blue strip.

Update: I've been screening prospective tenants like crazy!

I know it's like scraping the bottom of the barrel, but you do occasionally find the qualified, good quality tenant along the way (Mostly for seasonals).
