Hi there!
I agree with you guys as well! You should certainly find out what tasks are taking you the most time, but also think about how easy it would be for a VA to complete those tasks with minimal to no supervision after training. I have been working in the virtual assistant business for quite some time, and I can tell you that it works quite welling you can provide some sort of checklist or template that your VA can work from.
Most real estate professionals that are looking for a VA typically outsource work that is not limited to but including: filling out paperwork and reports, sorting through emails, responding to emails, reviewing and reporting on data, customer service and much more. As far as expectations go, you should certainly expect that things get done exactly the way that you want. You should just be sure to have a phone conversation to ensure that your needs are understood clearly.
I see that another colleague recommended sites like fiverr.com and upwork.com, but the problem most of my clientele have found with these sites is that a lot of times there can turn out to be a communication barrier. And in turn, you end up spending more time than you should sending work back for edits. My clients love that we cater only to realty professionals and that we are 100% U.S. based because 9 times out of 10, we have dealt with the type of work that you need done, and communication is made easier.
If you have any additional questions, I am more than happy to answer them, happy searching!
