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).

That's why multi family space is so crowded as you are diversifying your occupancy with multiple tenants..Most of the investors who consider this route already have high paying jobs or business that can handle a catastrophe 

We are back and forth on our decision on whether to make the new bathroom a two piece or a full three piece because the bathroom is very small with a sloped ceiling.Adding a three piece bath would increase our monthly rent and increase our homes appraisal however with limited space, we are concerned that potential buyers and tenants would be turned off by this three piece addition.If we decide to add a three piece bath, the shower would be 30" and the vanity would be a small space saver one with the toilet on the sloped ceiling wall.In your experience, would you do a two piece or three piece bathroom?

As of the 2017 NEC Update, GFCIs are required in all of the following areas:Underwater pool lighting (since 1968)Outdoors (since 1973)Bathrooms (since 1975)Garages (since 1978)Kitchens (since 1987)Crawl spaces and unfinished basements (since 1990)Wet bar sinks (since 1993)Laundry and utility sinks (since 2005)Crawlspaces at or below grade level (2017)Unfinished areas of the basement (2017)

Treat all space as rental space.

A conventional appraiser is unlikely to enter a crawlspace to check for foundation problems, or enter the attic to look for termite damage.

I want to know if I am I limited to using existing openings (doors, windows) to connect new spaces, such as a laundry room.
