Thanks @Brandon Sturgill, I'm considering an investment in NJ or PA, just not sure if the prices in the market are right, don't want to buy something that would be worth less in a year if the market goes down significantly, especially for a first investment, and to be stuck with it for several years till prices are back where they have been.

The reason I am asking , if whole seller come back with counter offer (which is highly unlikely), is it worth considering it. 

I haven’t met nor worked with this GC yet so take my recommendation for what it’s worth , but I had a good rapport with this Polish contractor named Tomasz Balka.

At the time, it didn't seem worth it to work more hours in a low wage job when I had so much investment money at stake.

Sometimes the education and experience is worth more than gold.

One of the biggest problems I see for beginners on this site is they read about some story about a guy buying some property in the middle of nowhere for 70% of what it was worth and think they'll be able to go into a super hot seller's market like those found in California or Arizona and get the same deal.

So when you move out, its not worth keeping the place fully rented.

Ive came across and even recently found properties that are selling for 60-150K and worth 100-180 K as is.

As a rental investment it is not worth the risk or work load based on you having negative cash flow unless you are in a high appreciation market and willing to gamble.SFHs make for poor income property investments and are primarily a appreciation play.

It sold in 2014 for 80k the estimate for its worth now is around 90k.
