Hello @Calvin Pringles,
As I do agree with the points you have made. As I, myself have thought of doing a Accessory Dwelling Unit (ADU) instead of a duplex or triplex. Which as newbie to real estate investing and to Bigger Pockets just referred to them as In-Law suites. So thank you for teaching me something new today.
And as @Wale Lawal has mentioned that everyone will have their own "BUY BOX" (just learned what that was last week). And those ADU will have their own drawback.
Here are a few drawbacks I had thought of and if anyone would like to point out any additional drawbacks for ADU's please do.
Electric Meters: I doubt the even if the ADU is a separate structure they have a separate electric meter as they were mainly used for guests. What is the cost to have them installed?
Water Meters: Same as Electric Meters.
Permitting: Can ADU be used in such a matter? LTR, MTR, or STR?
Property: How much of the property is considered a common area? I know this is more preference by the owner. But what is best?
Calculations: As I again am very new to this. How would you even begin to make a calculation that this would be worth it for an investment? I recently saw a home with 2 ADU's one a 2/1 the other a 1/1. I have no idea how to do that math.
Those are but a few thoughts that I wanted to provide.
Good Luck,
Joel Di Piazza The new Guy...
