Great post @Taylor Burns!
I just found this post and thought I'd chime in because I only saw responses with advice on typical house hack scenarios - such as renting out rooms in your house, buying a duplex, etc. I've done both of those, and they can be great investments for sure, but they both have drawbacks.
Buying a house with as many BRs as possible, and then having friends move in and rent bedrooms is they way I started out. It can feel a little awkward since you're basically living with those that you're expecting to pay your mortgage. So I always ended up towing the line between my personal finances and my friendships. It worked for a while, but it wasn't extremely profitable for me. I really liked @Lia Martinez's idea though. Denver needs more of this, for sure.
Buying a duplex and living in half is a great option, but it's hard to make the numbers work these days due to competition with other investors and people looking to do the same thing as you. Same story buying a house with an ADU.
But there's another option that's slightly more off the radar if you're intending to live there too. @James Carlson brought it up, and I think he's got the right idea, because you will get more revenue this way...and if done right - not too much more work.
We just bought a house and finished a rehab to convert the basement into a short term rental with a private entrance. The private entrance is key. We now live upstairs and rent out the basement on airbnb. As long as you live in the house, Denver allows you to do this, and the licenses and taxes are super cheap. We have some STRs in Breckenridge as well, and let me tell you - those fees and taxes are INSANE. Denver's taxes and fees are very reasonable.
It's a 1 BR 1 bath, with a full kitchen and a separate entrance, so our place attracts travelling nurses, corporate guests, house hunters, and a lot of grandparents coming to visit their grandkids that live nearby. They are great guests, fun to host, and not as price-sensitive.
Going from long term to short term boosted income by about 30% for us. And now this arrangement almost covers our mortgage. The most important things are: neighborhood and location (when are they not?), having a private entrance, having a corner lot (easy access from street to entrance), and establishing yourself as an airbnb superhost as soon as possible.
Good luck!
