But the blessings and rewards outweigh the challenges and obstacles we face.

Purchase price: $115,000 Cash invested: $73,000 Sale price: $297,000 The home is a 3 bed, 1 bath, 1,184 SF rancher with a full basement and 2-car detached garage.

I wanted to share my experience planning, permitting and now building a 3 bed / 2 bath 800 square foot detached accessory dwelling unit (ADU) / back house / laneway house at one of my single family rental properties.

One in the kitchen next to the fridge (behind the cabinet in the picture below) and the other in the detached garage where the laundry machines are at.

Building a semi detached infill project is potentially a place to start you need deep pockets and significant financing to tackle something like that and likely partnerships as well.

Hell, the biggest obstacle is getting started at all. 

Ex: flooded basements, rebuilding porches, repair/replace heater, repair detached garages. 

If you find a home with a basement with it's own entrance or detached garage you could convert into a rental unit.  

Here's some things that have gone on here:A single family detached house had 21 offersA two unit property had 6 offers in less than 24 hoursA four unit apartment building had 11 offersA buyer put in a $10,000 escalation clause with no cap, saying they would pay $10,000 MORE than the second highest offerPerhaps you have similar tales from your area, I've never seen this strong a Sellers Market in my long time buying real estate.https://www.parealtors.org/bid...

My wife owns a starter home SFR detached in Gilbert that I remodeled last year and now nets $685/mo and also has 6 figure equity.It would be hard to replicate this today given the current price/interest rate circumstances in our market... but the deals are out there.
