If you are able to manage it yourself, I think you will get a lot of very helpful education in real estate by spending a least a year or two doing that.You'll be able to work with property managers a lot better if you've done the work yourself for a bit, and it also helps to get familiar with the various laws and regulations you have to comply with as the owner, even if you do have a property manager in place (e.g., the new RI rental registry and associated lead paint inspections/certificates).It's up to you whether you're able to do it, but I think you'll get a lot out of the experience if you can try it for a year or two.
