You lose everything you spent on tax lien and sub taxes and have to walk away.

I have a ton of hobbies that I don't make money on. 

What @JDmartin said.......You'll lose money unless you hire a good GC.

I would lend it out via hard money, which I'm currently doing, at 10%. 

What I mean is this Money market at Bank of America pays for instance 4%, the money market local Bank of Bricktown Pays 4.5%, an online outfit is offering 5%.

Ultimately tenants who pay on time will do so regardless of the discount, so you are probably just throwing money out the door by giving money to people who would just pay on time anyways.I do recommend a discount for electronic payment.

It's a great way to increase your net worth and these loans can also be used to pull cash out of a property as it appreciates allowing you to reinvest money into new deals.Happy to connect to discuss further. 

I thought of wholesaling as a way to get my feet wet and to build capital without having to use my own money.

If during the tenancy you decide to switch bank accounts to hold the deposit, you must give the tenant notice of where the money is being held within 30 days of moving to the different account.

Where should I save my money?
