I often use this to help calculate some quick math on deals.

When I had a secondary structure demolished a few years ago, I did discover the lot was zoned that I could rebuild another multi-family building on the lot if I wanted to.

So we were about to leave, and one of the secondary trainers pulled a bunch of us into a seperate room.

I have to agree with the math from @Don Konipol.

I bought under a secondary mortgage (don’t have a primary mortgage but 3 hours from where I live) and I put 10% down at 6.25%.

The math isn’t mathing.  

So there is inherent danger in commercial that never been talk about, becoz every GP is rushing to buy at discount->to rehab in hurry->to rent it out->to sell it quickly and do the same/repeat, this cycle can't be repeated in basic math because at one point, the cycle would go againts them.

But you’re right the math doesn’t add up.  

I do regular front house portrait first, then a secondary front if there is a wider one for the front setback, then front aerial (one, if you did them), then I always start with the walkthrough of the house to tell a story in photos.

It is all about the math and numbers now.
