Your trusted 3rd party has almost zero chance of buying your specific note.

I have a 6 year goal to retire at the age of 50.

Sorry I can't be more specific on the numbers. 

I have had 3 specific investor CRM's referred to me for keeping contact with leads as they come in:REI BlackbookInvestor CarrotLead PropellerI'm curious if anyone has had experience with one or the other of these. 

They can help you with your specific situation and they know current state of the market.

Though the tenant has yet to make a specific mathematical proposal, he has left almost a $1k past due with the water dept as the lease comes to a close and has proposed that this is the amount for making it right.

You can ask your agent, but they probably won't give be able to you super specific information unless you already have an area in mind.

IMO it depends as much or more on the number of people as the age of the property, and if the current owner is a mainainer or an avoider.

Andrew,I can’t say anything about specific refinancing, but The Farmers Bank has been great to work with overall on my personal mortgage as well as purchasing my first two properties. 

@Wayne Brooks  I don't know about your short sales.. but I know when my wife did a few and one specific I remember was a dentist who wanted to be a flipper  and was upside down about 100k.. the bank made him sign a prom note to release him.. so even though my wife closed the short sale the doc still owed 100k over time.
