I currently have my criteria set at 30% margin, which works great for my area.

I use 3% vacancy, 5% capex, 5% maintenance for this particular property (*Full Disclosure: my day job pays my bills, so in reality I'm setting aside 100% of cash flow, but some of that money will also go towards more purchases).

Executed a master lease with a one year option to purchase for a fixed price and guaranteed them a set amount each month.

You get to set the interest rate (it can be 0%) and you get your investment amount back sooner.Some things to think of: To file a deed at the county courthouse is $100-$150 in cost (depending on which county)And you want that note to be pretty close to 70% of the ARV for the property if you don't want to bring any money to closing. 70% will allow you to roll in your closing costs.

I have read the guide and set the alerts.

Tiller will automatically pull financial transactions from checking accounts and credit cards into a spreadsheet allowing you to then set up a simple financial cost tracking system. 

There is no set budget at this point...trying to establish the budget.

With less than $30/month CF, you're setting yourself up for big trouble.

I've got $100k in cash, clearly not enough to win the auction, and I don't have time to set up a line of credit - which I probably wouldn't be able to do anyway given what I've recently borrowed on a personal level. 

Also, set up keywords for your area and attend local meetups if they have them in your area.
