Old man died and the wife wants to sell the portfolio.

They are requesting to go month to month at the end of the lease term, I am okay with allowing them to do so with a slight increase in the monthly rent (My current lease does have an automatic renewal clause that would be month to month if no termination notice is received by end of the lease term, I just need an addendum to increase the rent amount).

Adapting to market changes.

Additionally, I expect applicants to follow instructions in the advertisement and application, to make and keep appointments, to show up on time for appointments, dress and behave appropriately at appointments, and in general demonstrate throughout the process that they are someone that is easy and pleasant to do business with.

If you aren't discipline enough to learn this on your own, the road to getting your real estate license will force you to learn them.

What’s the best way to attract buyers quickly without losing more money if we sell?

I hope to see y'all there!

Most of them are scams- best case scenario, they charge to a ton, you find deals and they pay you a pittance for bringing those deals to them. 

It needs to be in the classifieds.
