Buyer in the beginning did not want to be represented, buyer declined services from listing agency, LA accepted offer with buyers agent on the contract along with signed agency disclosure.

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

It is much faster and is way easier for the elderly tenant to keep clean.

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

Check out your market otherwise if it is clean and descent looking stay with your original plan.

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.

Dirty, needs some major cleaning on the inside.I'm happy with collecting passive income and having a steady paying tenant. 

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.
