The only means of contact that the county provides on the website (http://www.baltimorecountymd.gov/iwant/pay.html) is a phone number but every time I call I am just put on an infinite hold ( let it passively sit on speaker for 3 hours one day to no avail).  

.- Increase your HELOC (giving yourself access to the stock money)& stay with your strategy of using the HELOC to pay cash for investments, fix it up, Cash Out & do it all over again.If you're doing it right, you can have an infinite return on your rentals.

However, at this point your CoC becomes infinite as you have no longer any cash in this deal.That's how this game is supposed to be played.

The money is actually free if you use it multiple times, but only pay for it once...and when I say multiple times, I mean an infinite number of times, with each repeated use of the same funds reducing the cost of the funds per use.What you have is a goldmine...if you understand how to implement it...in other words, If you understand how money works

If you ask any big time investor out there they would answer as much money as I let them borrow and for an infinite amount of time to pay back the loan.

In this example, the deal is so rich that 70% of $140,000 is $98,000, which covers the purchase, the rehab, and leaves $18,000 on the table.The thing most people don't understand is that hard money lenders are all about the deal, and if the deal makes good money, they'll put money into the deal.  100% financing is going to cost you, but there isn't anything like an infinite ROI because you didn't put any money into the deal.

If I assemble my own lists from the property appraiser data, it will be infinitely cheaper.

I don't know Tulsa, but if it is like most markets, there are a ton of sub-markets, some of which are in much higher demand than others ... you have to pay up to get into those in demand sub-markets on the "right side of the tracks" but in my experience you usually get what you pay for and a great deal in a great neighborhood will outperform over the long haul with infinitely fewer headaches.

At your stage, invest in yourself and find a way to earn while you learn (return on sweat for now, return on investment later) ... no downside risk and infinite upside potential ... that will put you in a real solid place in the future on where and how to invest to max your profits while insulating yourself from any reasonable downside risk the market may throw at you along the way.

The second is actually much harder than the first, but they are both infinitely easier than spotting a crash in the short term before it happens with any sort of precision.
