I'm somewhat new to real estate investing myself in the sense that i have not yet done my first deal but because of all the knowledge i have gained from BP, blogs, podcasts and articles I know a lot more than I expected myself to know at this point.I had similar questions like the ones you listed because although i've lived on land the whole time, i never had the need to ask for the cost of lawn care, flood insurance, garbage removal etc.I learned that the water, sewage and garbage bill in my area was packaged together and i learned that here on Bigger Pockets, from the comfort of my computer.Of course, you'd be encouraged to get out and start looking at homes in person but Bigger Pockets definitely helps you get setup for all you want to accomplish in Real Estate!

We recently discovered that the tenant came back with a bogus complaint basically marking all items listed one being a place not "habitable".

You can start with previous BP forum and blog posts about multifamily investing.

For updates about Covid-19 in relation to REI business, you may see forums, blogs and this link: https://www.biggerpockets.com/rei/coronavirus-content-resourcesKeep on with your Real Estate education by browsing, reading, listening, building your network and BP profile too (which is a priority while you are here).

Its always nice to see people starting early and getting started in what most people will probably agree as the right place (BiggerPockets).I don't wholesale properties personally, but i know there is a lot of blogs, posts, and podcast to be found here that will help you learn a lot!

Otherwise, I'm sure there are a lot of blogs and other questions on this site that would give you a faster answer with other people's experiences.I wish you all the best and good luck!  

Have a look at BP's blog where new articles are published every day: https://www.biggerpockets.com/blog 4.

The first step is to become educated on all of the different possibilities in real estate, and find one that will work for you since you live in an expensive area.https://www.biggerpockets.com/blog/wp-content/uploads/2018/11/Best-Real-Estate-Books-Ever.pdf 

I wrote a blog on this for BP ( what to watch out for) knowing how many beginners read this site.
