Welcome to PDX!
Some of you are coming from states where Realtors are allowed to assist in the locating of a rental property, for a fee. Oddly, given the ridiculously low vacancy rate, Portland doesn't have a good aggregator. So, I put together a list of links to the various property management companies I know are out there, and update it whenever I have a few minutes. I have no affiliation with any of these companies, and am not a property manager. Remember to be safe: use a PM when possible, and if you find a deal too good to be true, it probably is. There are a lot of shady people out there taking your money to "rent" homes they don't own. Check the assessor page of PortlandMaps to be sure who actually owns the property!
First, check out this mortgage calculator and see if maybe you could buy, instead! If not, when you're ready to purchase, let me know!
