Your local hot spot installer will be able to point you in the right direction.

If you are up towards NY/Maryland, Philly is a big hot spot right now.

I can use my phone as a hotspot so that is super convenient.

Where  are the hotspots for b class homes with middle class tenants?  

Also look on the HUD Homestore...Akron is a hotspot for cheap properties.Keep me posted on your progress...

Is there any hotspots within this area that would cash flow the best.

I'm just a beginner, but my strategy going forward for finding small multi-families will be to compare the market rents to the home values and search for properties in hot spots. 

by and large if a parcel of land in any major metro city was on MLS  and did not sell then it was overpriced probably by a lot... or has some other hair on it.IN markets were new construction is viable and hot land deals sell in a matter of hours or days at the most to builders looking for lots.my take on Texas as whole ( not Austin though) is there is so much land that builders and developers have a lot of options and unless you have some sort of infill in a super hot spot  your dealing with a parcels with limited value or desirability or physical constraints for environmental or regulatory impediments.   

Hot spot with the Tesla factory and tens of thousands of jobs coming!!

I also read the thread that Matt is referring to which could be a hot spot.
