So finally I solved this problem last week and have been on a buying spree, but I have also heard that people would pay for someone to qualify for mortgages on their behalf so they supply the cash for downpay and (for example) I can just qualify for mortgages and in return hold the property under my name and get paid for it.

For MLS properties, it's just a stronger offer because you are accepting the property "as is".

Having a big wad of cash in a bank account certainly provides a level of security, but it doesn't have a great return.Assuming one does not touch what has been saved, is there a threshold where you start funding other areas with a stronger ROI (buying new properties, paying down mortgages, investing in the stock market, etc.).I realize this would be different for someone who owns 5 properties vs. someone who owns 100, or someone who owns rehabbed properties vs. someone who owns properties that will need a lot of work, but I'm interested in everyones thoughts on the subject.

Where does everyone recommend buying supplies such as kitchen cabinets, granite, flooring  and all other supplies at the best prices from.

If investors prepare to stand the storm which most seasoned investors do, then everything will be ok as the market will always come back stronger, at least history says so along with inflation

I drive by the house multiple times most days and he is there about 33% of  the time, every time he needs supplies he will run to the store with no forethought of what he may need after he finishes that task.

Vacation markets do have different supply / demand fundamentals.  

In fact, it had gotten stronger.

The coasts love OKC for many reasons, perhaps chief among them is the comparative costs per unit and the seemingly never-ending supply of renters.

I thank you all kindly and i have endless supply of questions waiting lol
