Since the potential properties can be removed from the list in last min,  my major concern is when i fly in, the properties i'd liketo bid on could be already invalid from the list at auction. 

This info will lead to several options being removed from possibility.The best software options are designed for PM companies and can cost a decent amount monthly.Here's some cheap options:Doorloop, Hemlane, Innago, RentRedi, Stessa, Avail, Apartments.com, TenantCloud, TurboTenant, Buildium

When working with Civil Engineering, Is it best to simple pick on firm and go with them, Or is the 3 quote rule in effect at this stage of the process? 

Anyone have great experiences with highly efficient, extremely effective PMs in the area?

HOAs are including the roofing, snow removal and trash rest will be on me.

I never do it with the intention of making a tax return longer and will, of course, remove unnecessary pages if they're truly useless.

This is the most cost effective strategy if you have a limited budget. 

These have been effective across both multifamily and single-family homes, and I thought they might spark some good conversation!

As I've learned more about analyzing properties I have quickly discovered we had to make some changes to our current rents and with changes going into effect next month the property will cash flow around $675/month, we only have about 7 more years on a small lean we have on the building, after that it should cash flow around $1000/month and be paid off with no leans. 

What methods are you finding most effective, or what are you hoping to try?
