We also have a few micro warehouse projects on our board  (1-3 acre small unit flex spaces).    

.- Garage/Backyard: Yard is standard Chicago size with above ground pool that takes up most space (girlfriend wants to keep, I want to get rid of haha).

I hate the SF rent by room model as an investment because it devalues your own personal space.

I checked in the crawl space and I see a few joists are rotten and need repair.

To build off Mindy's point, there is an Option 3 here and that's invest IN debt :)Might not be worthwhile until you learn more about the real estate space and get a deal or two like that under your belt, but just to give the thread more perspective, investing in mortgage notes could be a worthwhile fit for a similar situation.

On unemployment because of corona, work in event spaces with crowds in NYC so not sure when I'll be allowed to work again.

You make enough money at your main income so that you're willing to work a second job, and pay your employer for the privilege, because you think you have a chance for your own parking space and a promotion...which would mean more work on your part, but...

How long would it take to rent the space after they vacate?

I'm located in Northern NJ, just outside of NYC where both property values and property taxes are ridiculous so in looking to acquire my 1st property was leaning toward a BRRRR House hack situation of ideally a 4-unit; however, SFR is slightly easier to find better deals (not much better just a bit more affordable) in this area; however, with COVID hitting the area HARD (Hudson/Bergen Counties); will the idea of living with strangers in a SFR still be viable or will this virus make the masses lean towards wanting their own space that much more? 

I can’t take credit, mostly dumb luck.Not enough space to go into all the details but we closed on a duplex in November 2018 (units 6-7), a SFH in November 2018 (unit 8), a 3 duplex deal in February 2019 (units 9-14), two separate duplex deals in August 2019 (units 15-18), and a 2 townhouse buildings (4 units) deal closed in October 2019 (units 19-22).
