Same story for tenants - if you have issues prior to move in and a lease being signed, you don't rent to them.

If I had known this prior, I would have never provided our data feed to this makeshift company. 

If the prior owner made a lease with the tenants and you purchased the property (and the lease), I doubt you'll have much luck evicting them just because you don't like the rent amount or lease term. 

@Will Mejia if you reinvest prior to the end of the calendar year into the right type of property where bonus depreciation is taken, you may be able to reduce your tax exposure partially or completely. 

The other catch is you have to either document prior experience managing rental units or use a property management company if you need the rental income to qualify.

I am thinking  it was recorded by the seller or the wholesaler that was trying to sell this property prior to going up for auction but have no proof who it was. 

It would be advisable for the potential purchaser to thoroughly investigate every aspect of the property prior to purchase, including, but not limited to, the location of the property, type of buildings, if any, on the property, determining what, if any, liens or encumbrances exist on the property, and any other facts which may be pertinent to the contemplated purchase.

If the goal is to retrade after contract and prior to COE, you might have a shot if there was some sort of egregious delay on the seller side (e.g. on a recent project I had a dozen buyers stuck in escrow for nearly a year longer than expected due to issues with utilities), but even then it's a long shot. 

We still have land to build on and have all the infrastructure set up, mainly from our prior builds, to make it even cheaper.
