@Kev Li    is the large purchase something you are going to be able to pay back quickly? 

Probably also safe to assume it wasn’t investors bidding it up and most buyers aren’t investors and the buyers willing to pay the most aren’t investors.

Additionally, as reflected on your Appfolio Owners Statement, the tenant attempted to pay rent, albeit all 3 times it was returned as NSF. 

Some of the usual reasons why people would sell to these companies: If there is money owed on the house, the house is in terrible shape, you don't feel like dealing with selling it, or you don't want to pay realtor commissions.

What are you guys paying per sqft for per unit?

Debt is not a bad thing, and you can always use the additional cash flow from a property to pay it down quickly if that is part of your goal. 

Instead of resolving the issue, he’s threatening to place a lien on my property unless I pay him.I want to understand how does this lien work and this one example, I have such few examples with handyman, plumbers etc  they always keep threatening if you don't pay us we will put lien on your property. 

What documentation do you ask for as proof they can pay?

., just doesn't make sense to pay you extra fee to get what is already blasted there for ALL to see).

whereas most people do not respect utilities that they do not have to pay for the utility bill could get expensive in my opinion.
