Looking to see if anyone has done this before, and/or if these numbers look worth it:I have a long-term goal of owning a "snowbird" home in Jackson Hole, WY, but prices there are astronomical. 

I did not personally spell out an automatic rent escalator based on percentages, because in some years rents appreciate a lot faster tan 2 or 3%. 

What are your goals?

It is an interesting social relationship at play because you and your agent have slightly different goals. 

It's always a goal to get to the next step and into escrow and under contract but you should always have some contingency in place that allows you to back out of a deal if needed when you continue ypur due dilligence.Hope this helps!

Another point  is, evaluate what these investors' main goal is.

I'm definitely nervous but excited to meet my goal this year of getting at least 1 flip this year.

I wouldn't worry about artificial goals set by the internet, just focus on what reasonable for you. 

What are your goals?

Those goals you have mentioned are very attainable on this site.
