It's a goal that never ends, unlike having a set $ # goal.It treats increasing assets & decreasing debts more equally & it's not overly aggressive which could encourage over leveraging & return chasing.I know hitting this goal at a minimum, when dealing with large numbers, over 20-30-40 years will get me well past a defined/limited FI number needed for "standard" retirement. 

And then before you hit that cap you will have moved onto bigger deals & commercial real estate anyways.

For a recent rental, i used an agent first and used their suggested ask of $2400 a month, we received no hits in the first 2 weeks.

I considered forming a C corp and having me and my wife take our IRA and "invest" them in my C-corp but I think that is not allowed.c) I have a 401k that could do it but the payment would be hefty I thinkd)  I have a brokerage account large enough to do most of the deal but liquidating the funds it's in would be a significant tax hit (not a tax professional  :) )e)  There is hard money lenders but I don't really know what impact they would have on my bottom line.f)  I have enough in home equity to do it. 

To even hit the 1% rule, you have to get $3000/month.

I was in the middle of the last unit rehab when COVID hit, so the cash-out refi has been delayed a few months.

Also a realtor and a investor. hit me up and we can talk some time.

Trying to develop something before it hits the market is a current strategy.  

If you are in the New Castle county Delaware area or Delaware county PA area, definitely hit me up.

I think @Andrew Boettcher hit on the most important element which is getting estoppel agreements.
