Knowing that I wasn't receiving much value for what I was paying, I decided to conduct research and see what else was out there that could provide most of what I needed at acceptable pricing (subjective, I know).

I suggest defining your goals and conducting market research.

We have had a Strctural Engineer out to the property and while we don't need to conduct repairs within the next 5 years or so, we will need to address both of these things at some point and it will likely cost us about 100k.Any advice on selling or holding for the long term?

To navigate, network with local real estate groups, build relationships, use online listings, conduct remote due diligence, hire a good property manager, establish trust, and use resources.

There is also a 1x per month count of kitchen items conducted by facilities manager and restock of cutlery, plates, cups etc.

I have many GC's who have placed bids on conducting a full rehab / even new build, and the area is in a great neighborhood with $400k homes across the front yard.

This is why its important to conduct your business correctly and make sure your insurance is in order (along with  any vendors who perform services for you) because a good operator does not do things where insurance coverage is denied. 

Every system you try will have flaws, or you may salivate over a feature that appears in other software.Some familiar names are mentioned frequently: Stessa, Apartments.com, RentRedi, TenantCloud, Innago, RentManager, Avail, Rentec Direct, Doorloop, etc.I recommend conducting thorough research on each app online to understand their offerings, pricing, etc.

Anything would be appreciated as I conduct this research on it.

Tenant screening is more than just reviewing applications and conducting background checks; it’s about ensuring that your property is leased to responsible tenants who will treat it with care and respect.
