For example, if you want to concentrate on just doing wholesaling,  find a group that does JUST THAT!!

Right now I am concentrating in the Philly suburbs. 

You're correct that the Clark/Fulton area is a bit rougher and is known for having a higher concentration of Section 8 housing.

Therefore, identify a tenant segment with a high concentration of reliable people through property manager interviews.

We've negotiated some in a portfolio where a certain house will be at 25-30%, maybe even as high as a 35% but the loan is less concentrated in houses with less of a downpayment(10% needed for a STR). 

This strategic use of financing and leveraging equity has been crucial in scaling my real estate investments.Key Lesson #3: Diversify Your Real Estate Portfolio Early in my investing journey, I concentrated too much on a single market or type of property.

Use MMR available at home depot. 1 product will kill the mold, but the stain remains, the other will remove the stain (super concentrated bleach w surfactant) so, you will need ventilation as it's strong. 

Concentrate on making first the hundreds of thousands in equity (owned equity, not financed property!)

Home ownership will get more concentrated. 

It will save you a lot of valuable time so you can concentrate on growing your investment portfolio instead of crunching numbers.This post originally appeared on the BiggerPockets blog.
