I want to be ethical and care about people.

The way you opened the topic left me thinking that you're asking a moral/ethical question, like "how do investors sleep at night?".

@Danielle ThompsonIn a one-meter property, the OWNER pays--check your laws--are you sure it's legal (or ethical) for you the split the bill 50/50 between the tenants? 

I'm sure you will get different opinions about this but this the ethical answer. :-) happy Wholesaling!

And, a subject I have not seen here is: ETHICS!

I've also written extensively about this as I am also an Agent/Investor who is a Broker in Arizona.Put simply, the pro's are thus:Access to MLS Deals (Pocket Listings, and otherwise) Access to the Expired and Cancelled Listings (GREAT potential leads without any competition) Reliable, quick information about pricing (asking other agents and MLS) Agents become your Buyers.If you are a Realtor®, you know that the National Association of Realtors® Code of Ethics will ensure you get paid on referrals.You have multiple streams of income as you are able to both represent others as well as yourself.You are able to use that as a "Stick" against other Realtors® and Wholesalers in competition.Of course, there are cons...It does cost to get a license, to maintain it, and pay regular dues.You must be associated with a Brokerage firm (I've written articles about how to find a good one) You must provide comparables (the Code requires it) You must use a State Contract (Again, code and standards) You must disclose your Principal nature (code, state statutes) You must disclose your intent (to flip, assign, or any of the above.)In the end, I think it's worth it.  

I completely believe in real estate, I just don't have any capital, currently investing in stocks but not actively, or a stable job, just a Pharm tech license.I have been actively listening to bigger pockets for two years now and read some books including Robert Kiosaki's "rich dad poor dad", I still listen to Joe Fairless, I want to get started but I don't have much experience, only thing I know I do have of value is, that I am a hard worker and will do whatever it takes to get into real estate investing, as long as it's ethical.

Is it ethical to use a tenant's security deposit for repainting and cleaning or regular wear and tear?

Buyers are going to offer what they're going to offer based on the quality of the work and the market.The appraiser can't ethically reduce the value of your appraisal because it's a flip.

I have an "abundance mentality" and a strong work ethic.
