TIA.Hey Hunter, I'd recommend Tyler Hay with Ohio Renovation Solutions.

I am seeking recommendations for an app that can integrate with multiple platforms.

Recommend you don't make an offer. 

I also recommend not allowing unaccompanied showings if at all possible.  

My recommendation is to save money through your W2 until you not only have enough for a down payment but a reserve for repairs as well.

BP has done such a great job of promoting SFR investing to the masses, that those masses have pushed up real estate prices to where it's now DIFFICULT to cashflow right away.Keep going, but understand you won't get rich in real estate overnight - it's a long-term wealth building strategy.For the short-term, recommend joining a few in-person investor meetings if possible, otherwise online ones.

BiggerPockets also has a calculator to analyze deals, and I highly recommend you start this as soon as possible, even if you are not ready to buy.

Quote from @Sarah Kensinger: I have never heard of her before but recommend a number of other STR designers.

However, I don’t yet have the funds for a down payment on another house, and I’m trying to figure out the best option for where to live while I rent the apartment.Do you have any recommendations for managing this transition or tips on finding a temporary place to stay?

I would highly recommend you create an LP agreement.
