Principle paydown is something that a lot of people gloss over, but your interest rate and loan balance play a big part in this. 

They indeed got a response-rate of close to 50%.

This rate depends on how fast you're running the dialer, the type of data you're using, the number of times you have cycled the list, how many DNC's have been removed, etc...

The implications of this are extraordinary far reaching imo, however I want to focus on something much simpler, Buyers, what would you think is a far rate to pay your buyers agent out of pocket, or possibly rolled into your loan?

~I have a 2.5% interest rate on my primary house I do not want to pay off and 200k in equity. 

As rates continue to decrease, more investors will come off the sidelines.

Then it will receive feedback from data such as click-through rates and booking rates to determine if it is a top property.With this I suggest that you take time during the slow season to scout your competition and upgrade amenities and photos to put your best foot forward.Obviously not everyone has the luxury to do this, but it will give your listing the best chance to take its place among the top results for your sub-market.Others may have valid opinions to the contrary, and I suggest you consider what you know about your market.

You can check out an App called Shuk Rental Marketplace and get rated by your tenants (and rate them too).

The rate I'm assuming is bad (9.25%).

Each class has different tenant pools, appreciation, turnover rates, etc.
