My mother is a realtor who is nearly 60, exercises regularly, but wouldn't stand a chance in any sort of hand-to-hand combat.

Only 2 hours of sleep last night for me or you know I would have pulled it back out and dove right in.  

Bought a white-picked-fence forever house while in involved with a biz startup, had a regular job and nice schedule, but soon needed more excitement.Now manage a lakeside tiny house development, involved with property management, association management, real estate sales, social marketing and basically my little LLC owns me> Argh!

@Aaron Stuiber hey man RE never sleeps and neither do I. 

I typically stay in the regular forums and have content there by answering questions.

But I would still probably keep $10k in reserve just to make myself sleep better.The 6 month rule I like because that tells me I could last 6 months with 100% vacancy.

I consult regularly with my clients on the use of the 401K and IRA funds in real estate.

And a lot of these brokers call them on a fairly regular basis asking if they are thinking of selling.  

There are advantages and disadvantages to both approaches.Equity participation in a flip transaction is considered a trade or business activity, and if your plan will conduct such operations on a regular or repeated basis, you will be creating unrelated business taxable income (UBTI).  

I can't sleep or put down the phone!!
