I generally advise against townhomes and condos as the HOAs can become harsh and limit your options.

Considering you have just bought this property and inherited the tenant, I would also consider finding some ways to be in good standing with them before proposing the rent increase, they might not take it so harshly.

It's a harsh reality. 

Also just knowing the area they are in to see if its worth pulling the trigger on.

This will trigger tax consequences!

This is usually too harsh for a single incident, particularly with a new tenant.2.

Even if I raise it from $600 to just under $1200 in the span of a month the tenants have no where to go because I will still have the cheapest rent in a 5 mile radius.Though, I don't want to be too harsh as I have been in their shoes before, I will work with them on the rent raises.  

Just make sure you have a real investment plan laid out because it doesn't benefit you to pull the trigger just to end up losing money every month or losing the property because the numbers don't work.

Just haven't pulled the trigger yet on any one course. 

Reviewing their product page it does appear the $25/month is base with the marginal $1/unit pricing after that. https://latchel.com/emergency/So more economical as the portfolio grows, though very curious Your XP once repairs are triggered since most after hours calls would be “surge pricing” for any contractor they bring in. in 15 years I’ve only had a few of the stereotypical “after hours broken toilet” calls, but I know that’s highly variable by location and property class.
