Being a Broker myself, if I plan to sell, i will do the selling myself.

Tenant told me the owner of the property she's currently renting is selling and she needs a new place.

that's the sale pitch about the "tax efficiency" of equity investing in real estate).Note: don't forget / freak out about when you have to sell and pay back that depreciation.Good luck.

Is it more difficult to sell? 

Stocks are pretty liquid, BUT selling them triggers tax consequences and the timing of when you want the money for real estate purposes might not coincide with the best time to sell the stock.

I have a 4-unit outside of PGH that I'm probably going to sell this year.

I hold a number of 4-plexes in my personal name and am considering selling them to purchase a larger multi-family property.

@Todd Dexheimer Hi Todd, you sound like someone that sells 30k mentor packages lol.

I understand now that this is likely because I am looking in areas that are too 'nice' that are selling at a premium, and I need to focus on towns a tier down from there. 

If you don't want to sell, reduce the rent, or extend the lease more than 12 months at a time, then stand firm.2.
