If you think they are illegally advertising your property I think you should first text or call them and ask how much they are selling it for and when it is available.

One of the most important/difficult tasks is finding quality tenants.

After each task?

no, it is 100% legal (and friendly) for non-local to purchase in many areas, and foreigners might obtain a visa permit to live, in other areas it is illegal, but some non-local do it anyway, they use some laws which is risky and the law is grey in these areas.

I’ve used apps like Shovler and Task Rabbit but you have to hire out for every snow storm.

So don't get too giddy at a minor milestone, and keep pushing as you did from day 1 until you complete that task.

I just recently dealt with this scenario on a recent purchase.  4-plex with an illegal 5th unit at the bottom of the building.  

Hey, my name is Miles, I'm 28 and I have been living in Austin Texas for 6+ years.I currently work as a handyman mostly doing small "tasks" for new residents.

@Assad Oskuei my experience has been that the city really doesn't like approving permits for finishing basements if it looks like someone's going to try to add an illegal unit there.It could be that the unit would be illegal because the property already has the maximum number of units allowed (or grandfathered in).

I don’t personally ever operate illegal units because if something were to go wrong and you have illegal units you’re going to have an issue.
