It’s likely to at least pay for itself or help the property sell faster.Talk to a few local agents to confirm how much buyers in the area value a garage.

Quote from @Casey Graham: @Corey Conklin thanks for the follow up on this and the confirmation it's workin. 

Comments like "this area has nothing else like this" and "it just flows so perfectly from room to room" confirm that following what the house called, not what the area called, worked! 

Since this four-plex is in my region, I will be the one taking care of maintenance and management while the investor won't have to worry about anything but to receive the money haha.Let's confirm a few things before you get questions from a bunch of other folks on the forum.How much of your own cash/equity are you planning to contribute/invest to this deal?

[I think someone else provided an example of this case earlier]-Now provided you do qualify for purchasing a house (4 units or less), you will have no problem qualifying for a mortgage with a Schedule 1 bank as long as you provide the down payment (35% minimum of purchase price) and confirm proof of fund and the source of it- On the proof and source of funds, the banks would want to see an income enough to cover the mortgage payment and other expenses. and in some cases, they would want to make sure they know how you're going to cover your expenses (housing, heating, etc..) where you live.This is usually where it gets annoying for some folks but if you can satisfy this, you should be able to qualify for a mortgage just likely any Canadian tax resident, albeit you will pay a little more in terms of interest rate, etc.

And just confirmed by another BP member:

I got confused with a lot of the answers on this thread so thought I would confirm for you that the debt your partner gets will not be on your credit report and the debt will not negatively affect your DTI on new mortgage applications.

Because we confirm for closing that everything is as seller states, no default or anything janky. 

I can confirm first hand  it is Brandon Turner and I have not had a good experience. 

Still looking to understand the edge case conditions #2, #3 for the Austin property, and looking to confirm that no such fees would apply for the Garland house since they are not listed in the lease agreement.
