Screens happen to be one of my pet peeves, so I add them to my own annual maintenance inspection checklist.

Typically they will sit down with you and do a tax projection as often as you need, monthly/quarterly annually, etc.   

In California the property tax is based upon the purchase price, so lowering the PP will permanently decrease you annual expenses (thus will increase your cash flow permanently).

Certainly the loan scenario you described with your father makes a lot of sense.  10% annual return is certainly WAY more than he'll make with any bank. 

I realize he paid like 60K less and got way more (previous owner way overspent, wolf stove, spiral staircase the whole nine).

You need to look through the Wind Shield in order to anticipate if the road ahead is clear or if there are obstacles that you need to avoid.Once you understand how to Drive your Business (or Investment), you start to do calculations based on the future, such as 10 year projections with Annualized Rental Increases, Expenses Increases, Rates of Return, Discounted Cash Flows, Internal Rates of Returns, etc.The people who think you can't calculate the future somehow missed the education which clearly has financial formulas that are designed for that.I am hoping the readers of this post really try to think about why there are formulas like FUTURE VALUE (FV)....... is that just something in someone's imagination?!

The remaining annual income is yours, and you don't have to pay the capital gains or depreciation recapture taxes on the sale of your real estate.

I saved $58 on the annual membership!

Again use around $400K cash to buy a passive instrument that pays monthly probably 7-8% annually  and use the other $150K ish to purchase $400K of zero coupon TIC or DST. 

I am looking to buy/hold a building annually over the next few years and am in the process of looking for #2.
