Read the forums, see what others are dealing with (late rent, no rent, extra tenants, unauthorized pets, breaking a lease early, security deposit disposition, application screening, etc.) and create a list.

I am looking for an electronic screening, application, contract and rent collection system. 

Yes, if we screen properly and set solid guidelines, allowing pets can be quite profitable.

You need to be careful that the sale is "arms-length" and is not just a smoke screen.

All you will get is revenge...can’t squeeze blood from a turnip.

Property managers wont screen tenants as thoroughly as one might expect.

Compare the pricing options carefully, as you will find that RentecDirect is more all inclusive, while Buildium charges a-la-carte for certain features (online payments, tenant screening, eleases, etc). 

The mid 20 year old applicant has decent credit score with all clear background (cozy screening). 

Simply inform all applicants you do not want to accept that they are not first in line and that you are still screening applications and you will inform them in time.

Can anyone give me some advice on Tenant Screening for Mobile Home Parks?
