I.e. a property sold down the street with 1 extra bathroom and 250sf more.

It's easy to obtain, costs very little, and doesn't require extra, on-going effort to maintain.

Fix it up and rehab or flip and then you can pay yourself back and have a little bit extra to push to the next one

Im at base pay since I Just started, top pay at this job is at 5 years and we make 100k base pay, there are guys easily clearing 160k due to OT and other extra money functions. we also have a lot of opportunity to move up in position, Supervisors clear 230k like nothing so right now I'm not making much but long term this is one of the best city jobs to work.

And more photos taken, same photos, and extra photos of any damage.

Section 8 can definitely cause extra headaches like the longer wait times to get a tenant in there, the inspections, and the incompetent CMHA office you can never get a hold of.  

For the 4 plex you are spending an extra 80k in renovations (I question your 110k renovation number to get to 4 units - this could be low but I don't know the square footage or layout).

So as investing partners it makes sense because we will both have extra cash at the same time, we partner up to cut the risk in half + we both specialize in a couple things the other does not in terms of being a rental property owner (e.g. running the books + marketing vs actually fixing things).  

So if you want to handle the extra work, like cleaning, repairs and all of the calls and texts, then go for it.

If interest rates fall later, refinancing again might require you to bring extra funds to the table, which could impact your overall investment strategy.
