@Ryan WilliamsThis was my goal for years and I was on track to have my primary paid off by the time the kids went off to college.

In additional to conducting educational workshops, I also write blogposts for their websites.

Next, arrange a site walkthrough to pinpoint any additional needs or potential challenges.

My original SFR was 1100sf and I added 2 units: an 800sf SB9 unit and a 750sf ADU (converted garage plus addition).

Quote from @Lionel Quiambao:  ... and maybe throw in the option for the tenant for more speed at an increased rent to cover the additional payment. 

This combined with my new boss giving me additional responsibilities (how dare he...) and the support of my wife prompted me to take the plunge. 

Allen, you mentioned your kids going to college.

Are there additional factors you think are worth considering?

Additionally, in the R-7 and R-8 Zoning Districts, you need a Conditional Use Ordinance from the City Council to authorize the conversion.

It is currently a glorified finished attic with little room- Use addition and raise it up and extend it to the side of the home for more finished space and room for deck, washer/dryer room etc- Make the living space as functional as possible with the added sqft- Add outside living structures like deckThis is a fairly wealthily area and I want to maximize my ROIWhat are some things you recommend for a large scale project like this and what are some hurdles ?
