Would it be buying more of the same type of properties or expanding into larger properties?

People come here, buy, move away and try to keep the house as a rental.

Owner occ developments there is no value associated to the income approach so these props generally speaking will appreciate a lot more as the neighborhoods are much more desirable. builders the last thing they want to do is sell to investors if they are creating owner occupied communities.. rentals degrade the neighborhood and they will be sabotaging their own values to allow a bunch of investors to buy and rent out in their communities.So when you buy new builds keep in mind if its a build to rent community they will NOT appreciate like owner occupied neighborhoods.. might be best to find something already 3 to 5 years old where the stigma of renters dies down.. that would be best to protect your investment.

Investors were buying at below 4%.

Of course this all depends on if you are buying locally, right?

Along the deal analysis I am looking to buy and use Deal Machine.Sounds like a great plan! 

Yes Pittsburgh is a good choice for Investors who either live here or are remote as the buy-in is a lot more conducive than other more saturated markets.

Any investor or developer buy raw land lot (zoning code G) and go through the process with the city to convert to commercial use?

Then save up as much as you can and buy a small 6-15 room motel or partner to buy something largerHotels are really expensive to get into as well.
