There are some good duplexes and multiplexes on the market right now, depending on what it is that you are trying to achieve.

It'll be beneficial for achieving your goals.

What's your main objective that you are trying to achieve?

Quote from @Saab Saab: How do I find wholesalers to make deals  What is the goal you are looking to achieve in that market?

In my market, JADUs are regularly being removed when selling a property to achieve top price even though they can generate income.  

As property values appreciate and rental income increases over time, you'll continue to build equity and wealth.Overall, renovating and renting out a basement as part of a house hacking strategy can be a smart way to leverage your home to build wealth and achieve financial freedom.

How far are you from achieving that goal?

Many options can be exercised to achieve your goals. 

If you are building from the ground up and need to finance the build, you may not use a DSCR to achieve this since this is a loan for non-owner occupied, rent ready properties.

Pair that 110% with a 1.00 DSCR minimum and you will likely achieve the loan you are looking for.Now, the group-home aspect is another story.
