Thoroughly understanding your market is key. If I like a property and use Zillow to do the rent analysis I would likely not buy anything. Most properties being rented are owned by absentee owners who manage themselves or often use property managers. Property managers don’t like to waste time. They post at market or below market to get it rented quickly. If tenant is paying below market they are much more likely not to complain about issues, that means less work for property managers. I’ve seen this over and over.
It’s very important to know the exact rents you can achieve in that city, neighborhood and street. This way you know exactly what price to come in and when to back down if the prices are unreasonable.
You can buy a duplex for 550-650k in Sacramento, renovate the units for about 50-100k. Rent the units for about 3k each side. One side more than covers the mortgage but of course you are putting more money into the deal and managing large renovations- not for the faint hearted
I have a feeling rents are higher than you think considering overall Oregon rates but I could be wrong
