High rental demand (Section 8 too). 

for me, the ones that cashflow the most are the ones that I bought with 3% long term debt, they were new (low maintenance) and they are in high appreciating areas(just a bonus but does not impact cashflow).

Prices are high, regulations favor tenants, and finding deals that truly pencil out can feel like looking for a needle in a haystack.

Specifically the area I marked in yellow.Any help here would be highly appreciated.Thanks!

If Airbnb is your best option, choose a location with high occupancy rates and optimize pricing with dynamic tools like PriceLabs.

A high occupancy does not guarantee the lost revenue.

@John Sherwood The areas you mentioned are certainly high-demand areas, but they come with challenges.

I am currently working on starting a youtube channel that will teach what I have learned in becoming a builder, along with following some of my builds start to finish.  

Start at a higher price point (not too high maybe 10%-20% higher than what you expect to rent for) then each week lower it just a bit until you get it rented out. 

I own a 4plex there and I have one unit that has been vacant for about 4 months now and this seems on the high side of vacancy time.
