For a rental, there are lots of advantages to ADUs, and doing both a Jr and a detached let you double up.

Some will believe they can handle the transaction themselves and will either end up under represented or the listing agent will end up doing double duty to keep deals together.

Foreclosure lists I think can be determined at some sites like propstream (I've never used it so I could be wrong).3: networking with lawyers that do probate situation and/or divorce situations and want a quick close4: Owner occupant of a property on Hud Homestore - basically trying to help first time homebuyers buy - less competition5: tax auction and tax auction sites6: Offering on properties that have been sitting on the MLS for LONG periods of time and low balling them.7: Calling owners that have recently had their property pulled from the MLS.8: Wholesalers that are selling to you with an assignment fee.9: Low balling every property you look at on the MLS and seeing what sticks.10: FSBO with strong negotiation skills.11: MLS when you see the property really quick once it comes on MLS and put in a full price offer but it was mispriced low (I got a gem a few years ago that has probably close to doubled in values since 2020 when I bought it).12: MLS offers that you really want to ownI might be missing some others but these are the general classes of people that I have noticed. 

On a 15-year note, other people are paying for your lovely retreat, and after the loan is paid off, it could be worth double or triple what you paid!

To double your money in ten years you would be around 8% returns required.

The numbers appear to be double what they should be, but maybe I'm mistaken.

There are private money long term options if you don't qualify for SBA or Freddie Commercial but rates will be double digits for sure.Cheers!

It was difficult to find an insurer to finally provide full coverage at under $2k, about double normal rates for my area.

Looks like it could potentially double the payment making it really hard to profit from the property and keep it up to the level it needs to continue having a decent asset.
