This company calls it “capital stacking” but I have since found out that they’re calling it the wrong thing…credit or card stacking is what it is.

For quickie emergencies there are always the "18 months no interest" options at Lowes or Home Depot along with similar terms from your credit cards (those checks you can write for a 3% fee and then have 12-18 mos to repay). 

My property was broken into and there are signs of drug use, copper pipes were stolen, appliance control boards stolen, damages caused, camera system was stolen too, and much more.How does insurance look at this?

As long as you keep everything in a separate bank and credit card account, it should be fairly straightforward to track.

Also, note that a lot of the home improvement box stores have a credit card with 0% for 6 months. 

I am paying off a small LOC and 0% credit cards from the last property - this will take a few months.

But now he is staying so we decided to play the cat card, and told him that per his lease pets not allowed and if he would like to keep it we will need to amend his lease to include additional $100 pet rent plus collect additional security deposit.

I see they suggest offering the tenants the option of paying by Credit Card.

They have an ID card with your picture on it so you cant even sneak in guests. 

I have had property issues but they were never negative experiences with OCF, in fact, they proved to me that I'm with the right company.2018 was a busy year. 2 tenants moved out within a month of each other (one evicted actually), refurbish needed to be done, I delayed on the payment for that and the copper piping was stolen from one of the properties.
