There are 5 4plexes on lamb and Lake Mead on sale, in the same community. And some of the has been on market for a while. Does anyone know why?

Reading all the books and watching the Bigger Pockets videos, everything seemed to make sense on paper but was so difficult in practice.

I see so many assumable loan which seems like deal, but I am unable to take it as my DTI is high due to primary property etc. 

There are a couple newer companies charging something like 18% but they make the owners purchase their own supplies (TP, paper towels, toiletries, etc) and have all kinds of "additional fees" that seem to put them in about the same range when you take everything in to account.

Seems like my best choice now is to find a responsible mid-term tenant that passes background/credit check. 

To do a $100k rehab in 3 months will require things to do like clockwork and that rarely seems to happen unless you have a relationship with an EXCELLENT contractor. 3.

That doesn't seem like the right approach...

It seems like you might be ready for the next step and start rehabbing the lowest hanging fruit.

But due to 10 Tech giants , our economy is surviving and seems "healthy". 

It seems that the #1 issue for the sellers is not recognizing taxable income and the #2 issue is that they don't want to actively manage their next investment, yes?
