The later date if parties signed on different days.

I'll start with one item and give you more later if you want. 

If you bring a camera you can save a ton of time by taking pictures of the documents and sorting through them later and inputting the data onto a spreadsheet. 

Traditional has nice terms and long term security, much easier to finance individually if you ever think you might want to sell one of the properties for any reason because it's time consuming and expensive to separate it later. 

But if they want to rent to own, you can dictate the terms later at the sale. 

@Alberto Leonard you will want to work with a CPA who specializes in RE sooner than later, however you don’t need that before starting.

I'm sure you're not the first person to change your mind, and your realtor would rather know sooner rather than later so they don't keep wasting their time.

I'm working back from that now to see what the whole thing looks like between now and 14 years later, but I know it starts with the first purchase. 

I'll lose money for 6 months so you can move later is a suckers move.If the unit is 40% under market and you want to keep them as tenants, raise the rent 30%.

I started at 18 out of high school from the ground up, fast forward 3.5 years later I'll close 90-100 deals and expanding to another market.
