There are various services that provide sale data other than the MLS however many do not have as detailed information as the MLS. 

There are services in the city that make this an easy process, but I don't anticipate needing to use them very often. 

Make sure it explicitly explains the process for termination if you are unhappy with their services, but especially if they violate the terms of your agreement.3.

What i used to do to find services like that was to just find those people on google or google maps and give them a try (https://goo.gl/maps/JhUyEFKVXkH2) unless you can get a good recommendation.Typically, i would go over 2 or 3 different ones to see how well they communicate, how reliable are and how much they charge etc.

Or if you don't have the time to service those listings, then just get the leads and refer them to other agents for a share of their commission.

Because it is your credit on the line, you should designate the accountant/bookkeeper/servicer to collect rents and make payment to your mortgagee.

Thanks @Omar Khan,  those services would be avaliable from a local commercial real estate broker correct?  

Does someone have a script that could be provided for wholesaling services to a company like Patlive?

In saying that, depending on your level if knowledge, option 1 is probably a better one. because $3000 is not enough of a buffer to service the property if you need to repair things.

Work done prior to the property being put 'in service' is just added to your cost basis.
