Not only does it make the property look poorly managed, it's a great way to crack your main sewer line and leave you with a hefty plumbing bill.

Cracking and structural problems occur because the sinking of the home is not being 100% distributed but usually only localized causing an imbalance. 

When smaller PM companies don't have the resources, manpower, and processes in place...they tend to let things like this fall through the crack.  

Just have to stomach the higher rates for 2-3 years, break even (ideally cash-flow a tiny bit), and handle the PM during the roller coaster ride our President is putting everyone on.

Tiny house thing doesn't make sense to me btw because tiny homes aren't really good for appreciation, maybe only for cash flow.

Again, the key here looking for properties that need work so you have a better crack at cash flow. 

A property manager may be a hard egg to crack but once cracked (built trust or relationship), they can open many doors since they can be your advocate and have access to many homes.this is the case with apartment complexes.   

A lot of the sewer pipes here are old terra cotta and they can easily crack or shift over time.

I am selling some land and some tiny houses i built this year but you know how that can be.

And this one cracked me up: "We were sipping lukewarm coffee from chipped mugs, half convinced we’d made a mistake."
