we would have paid the 10% deposit and have had zero legal recourse to get the money back.

Landlords can enter a tenant's property for a variety of reasons, including: Making repairs or replacements Responding to a tenant's request Removing unauthorized window coverings Preventing waste of utilities Changing filters, testing, or replacing smoke detector batteries Inspections Helping with an emergency inside the unit Posting a notice of eviction"Research your state laws because some of your comments indicate a lack of understanding of the landlord/tenant laws where you are operating (like threatening the tenants to keep the security deposit if they don't respond to you, I doubt that is actually a valid reason to keep their deposit, or evicting for late payments, or charging the tenants for your warranty repairs because you missed your 11 month inspection window which was your responsibility, and it looks like your lease says you can charge up to 18% interest for unpaid fees, is that actually legal?).

(I guess that's what the $3K to $4K deposit is for)(3) Is it difficult to find private money @ 12% over 5 years to fund these deals?

Wise is an international bank that allows you to deposit and display statements in whatever currency you choose.  

Since mid August til now I have lost 5 tenants, well two left deposits and moved in prior to the month.

Hopefully, they don't go bankrupt lol - In order to get started with the process, I have to pay $1000 deposit. Fully

Only thing better would be initial deposit and then paid in full upon Certificate of Occupancy and punchlist complete.Of course, standard items should also be checked: licensed, insured, willing and able to pull all required permits, reference checks.I would also commonly avoid the cheapest bid you get.  

I suspect all security deposit need to go to the owner or a new PM..

I had a deposit on a Cirrus Jet and that was driving me to attain more income as owning a Jet is a 200k minimum a year expense.

You can also request a security deposit for extra peace of mind.
