In my area we have a ordinance which dictates what can be written in leases and what can be charged. 

The structure of the deal might dictate the price a seller will accept.Take for example a 10 unit building.4 options typically lowest to highest price offered:1.

If you hold for more than 1 year as a rental, then you sold, you would pay short term capital gains taxes at 15%.So your intent and your actions dictate if you will pay ordinary income + self employed, or if you will pay long term, or short term capital gains.

Like every other city, there are market specifics to each that may dictate whether a property is a good deal or not, the potential for appreciation, and the quality of tenants you might get.Good luck!

Similar to what others have mentioned I believe there's many different factors that dictate a persons living situation.

Your state code probably dictates that this means it goes MTM.  

The timing of their paychecks dictates how they pay and they are living hand to mouth- they don't have enough savings to pay when they should and don't have the discipline to start saving. 

This element ultimately dictates the ddesirability of the business and therefor its price.

However, if you don't dictate how they find the deals or make it mandatory to see where they have driven, then there are many bird dogs out there willing to provide deals for some type of finders fee.

How much capital you have will dictate investment options to some degree.
