Hey Stuart,
I definitely agree with @Ben Rhodin above, and wanted to add a little color to it with a home I recently analyzed.
I think that one of the main draws of house hacking (other than having low/no housing expenses) is the flexibility it allows the owner. If one runs into a circumstance where they want or need to leave their house hack, that opens up another room/unit for them to rent out, increasing their return/cash flow potential.
In the Denver metro area specifically, cash flow is hard to come by in 2-4 unit residences which is the more “traditional” house hack but can definitely cover a portion of a mortgage doing so. However, cash flow is much easier to come by in the Denver Metro market when someone rents their home by the room.
Here’s an example of a rent by the room situation:
There is a 5 bed, 2 bath home currently on the market in the Thornton area for 375k. I currently have a mortgage quote of my own at a 2.75% rate. Putting a 3.5% down payment down, my PITI is estimated at ~$1,930 inclusive of mortgage insurance.
According to a Facebook Marketplace search, rooms are renting anywhere between $650-$900 in the area depending on the finish, size of room, etc.
For example’s sake I’ll use $700.
Now depending on a person’s comfort to profitability scale, they may decide to rent all or just a couple of the rooms when they live in the home. In the situation you described, all rooms would be available to rent because the owner had to / wanted to move out.
In a perfect world of renting all rooms out 100% of the time, I would be bringing in $3,500 per month, which offers significant cash flow above and beyond my PITI of $1,930.
Obviously the world's not perfect, but I would only need to average 3 bedrooms rented out at $2,100 a month for the year to cover my PITI, and have a few extra dollars for maintenance. Anything above and beyond is added buffer and potential cash flow (and definitely achievable), not to mention principal pay down and tax write offs.
Here's some additional backup plans:
It is definitely recommended to have backup plans going into a house hack investment. For a long term rental, in a quick Zillow search of the same neighborhood, I couldn’t find any 5 bedroom rentals listed. But there is a 4 bedroom townhome at $2000 and a 4 bedroom house for $2100. Assuming a 5 bedroom could land me $2,200-$2,300 this long term rental approach isn't as good as rent by the room, butwould likely allow for break even but i
Another backup plan that was popular prior to the happenings of this year, was to Airbnb a space in the home. This house is located in unincorporated Adams County, so Airbnb is not restricted in the same manner as Denver County. This house has a back door that can be locked off from the main floor (like Ben mentioned above), allowing the basement to serve as a non-conforming second unit which could be “Airbnbed”. Obviously this year’s a tough one for Airbnb, but I just gave it a look for a similar instance. I found two listings for a basement unit in the area, one at $70 and one at $104 per night. If I was able to rent out the basement (2 bedrooms) at $80 a night for 15 nights of the month, that’d be $1,200 a month just for the bottom portion. If I achieved 20+ nights a month, that’d be $1,600+ for just the bottom unit. Coming out of the pandemic, both would be plausible.
In that same manner, you could rent the basement unit out in a long term manner for about $1000 a month, leaving three bedrooms upstairs to rent at ~$1,700 for a long term unit. Total of $2,700 covering the PITI.
I apologize for the long winded post, but just wanted to put it out there that there are definitely ways that would allow the owner to hold onto the unit should they need or want to move out in an expensive market. It’s important and recommended to go into an investment with a backup plan, and obviously it’s important to follow local guidelines/laws (Airbnb, egress windows, etc.), but if one can get creative it’s possible to hang onto their investment and even cash flow with the right deal when the owner leaves the residence.
