Hey Raj,
Sharing a little bit of my experience here in case it helps you. I bought a 4bed/2bath SFH in Concord in late 2021 for $810K to househack it. Pulled owner-build permits to convert a detached 450sqft garage into an ADU in July 2022. By hiring the subcontractors myself I saved a ton of money. The three quotes I got from builders were $165K, 190K, and $235K, but acting as the GC I spent around $90K all in. Finished construction in Jan 2023. The ADU now rents for $2100/month. I had the property appraised in Jun 2023 so I could remove PMI on the loan and the appraisal came back at $950K. As you can see, because I didn't overspend building the ADU, I was able to get positive equity once construction was finished.
I know this doesn't solve your $6K/month question but I figured I would share my experience here since you mentioned staying in the home was a priority for you and being interested in ADU-house hack.
Happy to share more details if you need them.
Kindly,
Byron
I am sure you realize that between late 2021 and June of 2022 that there was likely property appreciation.
In addition, your ADU addition was not hands off as you saved significant money acting as the GC.
question is whether the $950k - $810k - $90k = $50k is more or less than the appreciation in that 1.5 years. That would equate to 6.1% appreciation over 1.5 years or ~4% annual appreciation. I do not know the appreciation of Concord, but that would have been less than the appreciation in my market. Which would indicate that the ADU may not have even added enough to cover the costs with an actively worked ADU addition. In you spent the hands off cost of between $165k and $235k, you would definitely be starting with negative equity on the ADU addition. My guess is between $75k ($165k addition) to $145k (the $235k addition) negative.
Let's go with the ADU added the $90k value that it cost. It implies you did the GC work for free. I do not like to work for free.
Now if I use 50% expense rule and do not include cost of money. It would take 71 months to recover a negative $75k equity position or 138 months to recover the negative $145k. in practice the numbers are worse because there is cost of money. Either you have a loan with interest or you paid for it unleveraged and gave up other options to have obtained return on that money. Big advantage of RE is the accelerated return resulting from easy leverage so to have RE that does not maximize leverage is accepting reduced return.
Good luck
Investment decisions are not made in a vacuum. And everyone's financial situation is unique which is why you will never see me making statements like "you should" or "you shouldn't" in forums like this. These 50% and 1% "rules" are more like guidelines, and sure more experienced/professional investors like you may use them as hard rules but that doesn't mean everyone should.
To illustrate my point, I'll share a little bit more about why this project made sense for ME and MY financial situation:
I realized I didn't share this before but I received a CALHFA $40K ADU grant to help with the construction costs. I bought this specific property because it was in a great neighborhood that I wanted to live in and I intended to stay there for at least three years. The ADU conversion and house hacking strategy were second priorities for me. I didn't see acting as the GC on the project as working for free. Not only because there was little actual "work" to do but also because I wanted to do it. You see before this I had zero experience with construction. I'm of course no expert now but I certainly am happy to have learned valuable lessons by doing the project.
Now, I did run scenario calculations at different stages of this project but I didn't adhere to the 50% or 1% "rules". Despite that I were to sell this property today I would realize the roughly 30% annualized ROR. Taking into consideration both qualitative(unique to me) and quantitive (some unique to me) factors I'm pretty happy with my decisions.
Kindly,
Byron
