Finally, you need to determine how much time you have to allocate to real estate each month.

etc....Well, if you use the 50% rule to guesstimate the expenses, any debt service or funding costs are not included within the 50% of rent allocated to expenses - private lending fees don't belong there.

I learned that in '08, '11, '15At minimum, we should diversify, pay lowest fees possible, rebalance regularly, allocate based on risk tolerances and time horizons and maintain a cash position. 

There're various methods to figure out the percentage, none of them is exact, obviously.Most items will be allocated 60/40.

I'd have to disagree though on allocating a grand total of 15% for vacancies, maintenance, and capex. 

But you can combine them into purchases allocated the proceeds any way you want. 

Our company is not cheap, and our employees are expensive but, since we are fully staffed we can allocate 3-6 people per job and stay there until its finished.  

If so, you'll probably need to set up an escrow account and allocate a portion of the rent towards the monthly, quarterly, semi-annual or annual premiums when they come due.

Such a release fee is necessary otherwise you may be required to pay more than is allocated to release a property.

Well Robin (LOL), your equity has all ready been allocated since you don't have it until the deal is taken and done, otherwise it's cash waiting to be used and yes, that has a cost, financially and economically.
