If you win the bidding on a $2,300 lien, your bid is cancelled since you don't have enough money.You have to pay the balance of what you owe for liens you win in 24 hours - again via ACH (some counties may accept wires).

I bought my first home [a rental] with a zero balance transfer from a credit card offer I received in the mail.  

I really like the fact that they pre-fund their investments, meaning that if the investment stinks and no one funds it, they will be stuck with it on their balance sheet.

That way, if the balance of the rent is not paid, there is no question that I can move to eviction as soon as the law allows.

You need to understand and follow the rules.The only way you can access your 401k funds to invest in YOUR project is by taking a loan from the plan, which would be limited to $50K or 50% of the balance, whichever is less.401k can invest in its own projects or someone else's, the rules prohibit any transaction between the plan and Disqualified Person. 

You can take a loan out for either:- 50% of your account balance UP TO- 50kUsually pay back within 5 years max, payments starting soon after loan is taken out.

Personally, I don't think they live comfortably, but that's using my criteria of lots of rainy-day savings, good health coverage, ability to eat at any restaurant I want without looking up my banking balance first.

Why are you interested in seller financing to a tenant when you still have a outstanding loan balance?

Therefore, it's all about controlling risks and balancing this with the cash flow and quality of life for your tenants.1.  

However in an attempt to get this cleared up I contacted her and she said that during that time she received no money from him, in fact she said that she never carried any balance for him.
