I was using Google sheets but I wanted to keep track of project costs and what I was spending on turnovers and it was getting overwhelming to manage, plus I couldn't store documents or receipts in there.

You can google, or even search these forums, for multifamily syndication and find countless companies that let you invest in larger scale properties, without the active management of direct ownership. 

Just google the sheer number of legal cases where literally this exact thing happened.

Google, and so on.

What you are proposing is called mortgage fraud, so the answer is no.As to calculating your mortgage, use any mortgage calculator (app on phone or google one).

If you need anything or have a question, you can just throw it out on one of the Google groups and your question will likely be answered within minutes.

A few months ago I laughed when bidding was up to $40,000-ish for a property where the house burned down ... google maps still showed the house but these bidders didn’t bother to even drive by the property in person; the lot wasn’t worth $40k.

I currently am doing a 1300 sq ft 2 bed, 2 full bath, half gut with all new electric, new framing, mostly new drywall, move a structural wall with nice finishes for $80k.As for where to find cheap labor, Home Depot, Floor and Decor, and just searching google and calling. 

If I set up a Google voice number for my tenants, and there's an emergency after hours, do I need an additional google number for them?

Im fielding property management now, and purchased 'Long Distance Real Estate Investing' book to aid in what I should be asking/looking for.
