Plan to owner occupy and hack and make upgrades while i live there.

Use natural move outs to upgrade and raise rents.

It's only $100 or you get it included with your Pro upgrade.

There is a low occupancy because at least 10 units need upgrades and it's poorly managed but if I fix that it's a great property, in the area the vacancy is between 5-8%.

Again all stud-framing completed throughout, a finished basement is in rough-in phase, and all electrical is roughed in-complete, including an upgrade rewiring new 200 amp panel completed ahead of the electrical inspector. asking only 199k. 

What level of upgrades are expected for the price rent will bring in?

If so, I would probably save up more or whatever you have to do to get into a SFH now instead of hoping your townhouse appreciates enough for you to "upgrade" later.

I just closed on my first property , a 75% rented (upgrading one unit) four-plex with some good cashflow.

A common one is that the electrical is expanded above code and a panel upgrade with a potential new electrical drop is required. 

The only differences between my house and the one sold are I upgraded the following: a/c system, luxury vinyl plank floors on the first floor and small items such as pull knobs in the kitchen and interior/exterior door knobs.
