I have a mix use building in CT. the ground floor tenant is a bar/restaurant that recently moved in. they got a $2M General liability insurance and is asking if that's enough. or if they should get an umbrella. the property is valued at around $700k, fyi. where can i read up on best practices for such a case?

Go to Etsy and search for "rental property tracker," and you will find hundreds of nice spreadsheets to track 10-20 rentals, usually for under $10.Software has extremely helpful features like online payments, marketing syndication (click a button, and your property is advertised on multiple sites), electronic document review/signing, maintenance tracking, and owner reports.

Sadly, it’s sat on the market too long and I’m looking to get creative with bringing the attention of many buyers looking for a good deal on a property (online auction or something else with tons of attention??)

We currently have 105 units and are using a variety of excel, google docs/sheets/calendars, apartments.com (ads and rent collection), docusign and QuickBooks online (which we would like to keep). 

A professional contractor is not going to work with you buying parts that don't fit online or at Home Depot.Who pays for delays?

What are some best practices when working through due diligence at the phase of projecting cost?  

Quote from @Lisa Broderick: Crazy that anyone would think that's a good investment.I learned what I needed to know by reading a few books and asking questions online.

There’s probably asset protection specialists/firms  who will side with your approach but it’s not practical and they are just  fee collectors. 

Conversion rate is extremely low when you get started BUT it will give you good practice speaking with sellers who have a ton of objections.
