Zoning and Environmental restrictions can greatly effect the value of a property. 

If you didn't pick a tool that quite obviously works because of a factor completely unrelated to the effectiveness of the product, my course can't help you, ..

Reason #1:  If you're not careful even a bad lawyer can get it turned into a purchase, with all of the rent credited to the purchase. 

Lot less multifamily which is why I haven't bought but it is where I grew up.Make sure you study the eviction laws, I believe tioga County (but could be a different close county im not sure) my lawyer told me that you now HAVE to pay to pack up an evicted tenant professionally and store it for months at your own cost if they leave their stuff behind.

Other than an intro call, I haven't started working with my lawyer, so that's why I haven't asked him.

I would recommend hiring a lawyer for a non-monetary default eviction.

What makes it slow in this case is that you don't really start seeing real cash flow until after year five but it's more effective than rentals in that there is little to no maintenance.Sure you can live in a home while fixing it up with the intention of selling it for a nice profit later but I think many people are already doing that and the buyers of slow flips now also have that opportunity without having to qualify with a bank.

(I am not a lawyer so none of this is legal advice but have seen similar situations occur). 

I do think its more effective because you get to see whats out there. 

(you know all the things we using in running effective and efficient private companies) it would be a different story.
