Hiring someone to do the work will likely cost too much (I would charge a small fortune, it's an incredible amount of work) and doing things as cheaply as possible will bite you in the *** later when you start having issues with your own shoddy work and/or materials.

The monthly payments are great, but the issue I am running into is what to do with idle cash.

This is a very common issue in parts of Milwaukee and I have done lots of basement reinforcing on our rentals.

Numerous times I have been able to think through an issues that arose on a construction site and saved the Owner by proposing an alternate route to resolve it. 

Based on a quick answer from Perplexity it seems like there would be no issue with you buying the home and collecting passive income, but you may not be allowed to manage it yourself since that is considered active work.

Some part of these neighborhoods change drastically, but the main issue is the amount of supply.

Its been a wild ride though doing all this through massive inflation and supply chain issue and Covid..  

So I wouldn't recommend them unless time isn't an issue for you and you don't mind waiting a few days for a response.  

But in my opinion, the biggest issue I see with folks jumping into their first "big" multifamily deal is the quality of the pro forma. 

I remember years ago our attorney reviewing one such issue for a client that was coming over to us.
