Unless you fall under the new JOBS act exemption for advertising, you will be limited to people that you know and have a relationship with.

By advertising, targeting distressed sellers/properties.

That is where I draw my take on Sell/Rent my biggest fear is the "What if Factor" - drop in tourism, association comes under litigation, hurricane (This season looks like it will be "Very" busy), Sickness or health issues or other.

Go to Etsy and search for "rental property tracker," and you will find hundreds of nice spreadsheets to track 10-20 rentals, usually for under $10.Software has extremely helpful features like online payments, marketing syndication (click a button, and your property is advertised on multiple sites), electronic document review/signing, maintenance tracking, and owner reports.

So now I mainly just use it for the rent collection, and I use Zillow, craigslist, and Facebook Marketplace to advertise my rentals.

You can't advertise yourself in the forums, but you could upgrade to a Pro account and fill in your signature so every post has some marketing, and you can always include "As a property manager in Denver, I address this problem by..."

@Brandon ClarkI am very sympathetic to CA investors wanting to invest in lower cost markets... but just to be very direct with you: -OOS is a LOT more challenging than advertised; and-50K is not a lot to start with.I genuinely think you will be more successful in a higher cost market that you can spend time in, rather than a random ,"lower cost" market thousands of miles away where you find something that looks nice on Zillow, spend your entire $50K on it... and then it needs a big rehab you weren't aware of, and you're negative $27K in year 1. 

Currently I found this advertised price from a Bay Area booklet I got in the mail

Upon personal inspection, I often find terrible workmanship.For example, I saw a "newly renovated" property advertising it had central air.

Each market has its own dynamics and risks, so spreading your $5.3M across Hawaii (Kona), Miami, and Honolulu could be a solid strategy.For the short-term rentals in Kona, Hawaii, the tourism industry there is pretty robust, but do keep an eye on local regulations and potential changes in the vacation rental landscape.
