If the intended zoning use is office for instance and you drive around and a bunch of office is vacant to 50% vacant then not a great sign for you.

Probably not a whole lot of money in this one instance but be prepared to argue additional junk fees and bogus repairs in the coming months. 

For instance, unless you are buying 4 identical houses, you will likely not maintain the exact same basis in each.

For instance, if you had the choice of purchasing House "A" for $75k that rented for $1,000/month (which is 1.33% and your exact example), or House "B" for $75K that rented for only $675/month (less than 1%), which would you choose?

We have had one instance where damages were caused by a pet and it was a minor very minor issue. 

In another instance, a credit partner got a $2M rehab credit line - this is what we've used to buy my biggest rehab deal (see #3 above).

You don't need to pay all cash in most instances as you can finance and close these properties in 30 days.5.

For instance: if the rent is $1,000 and has not yet been received a late rent notice should be sent.

So For Instance.....

For instance, the reason why it's a commercial loan is because they offered purchase + rehab financing for houses that wouldn't qualify for conventional lending.
