I purchased both as a package and for the next six years enjoyed great cash flow as I paid the tax on the house lot annually at about half of what it should have been and neglected to pay anything on the tennis court lot.  

Also, make sure you have a great property management company who can be your "boots on the ground".

Delayed gratification pays off!

Coin jams are going to be your second biggest headache unless you invest in those fancy ones with tap-to-pay but those cost a pretty penny.

You put on a new roof for $30K but the market won't pay you a $30K premium just because of it. 

I took the next 5 months to tackle everything myself spending approximately 17k in supplies and tools + paying a plumber and roofer 4k total to fix those issues.

@Lauren Ruppert  Cash out refi only in the husbands name which will take the ex wife off the financing/title and use the cash out proceeds to pay out what is owned to the ex wife.

Most brokerages will pay around 25% of their commission when you refer a buyer/seller.

Plus, you have to pay the cost to be the boss.

So, if you have 10 units and you are going to pay $1,500 a month and you are working on an active income job, too, this is an easy switch due to the labor mentally and physically (even if it is just phone calls) to get these rentals running as a well-oiled machine.
