I am willing to learn about other methods of both generating capital and cash flow, though.

What do you think is your most effective method of lead generation?

After a number of years you will get an idea of the percentage of expenses for your property, but experience shows it will be close to 50%.Also, replacement reserve is a method of setting aside funds (usually in a bank account) to cover a rental property’s anticipated (inevitable) future capital improvement expenses.

A very smart lady (@Jessica Swingle) recently said to me that many investors wouldn't buy a property where they wouldn't want their mother to live.That's one investment method and definitely good advice.

Her methods on targeting Probates are the best.  

The last scenario is fairly easy to resolve but the other can be very involved, using proprietary methods.

I found a broker that goes to distressed properties on auction lost and asked to buy it and then wholesales it, is anyone familiar with this method or have advice on how to make money with these deals.

I have found craigslist to be a pretty good method, however i have noticed that some would like a pm certificate to go along with experience. 

(I ask this because my current tenants pay me by only TWO methods that are SAFE for me--electronically/online or direct deposit in a special bank account)--are appliances tenants or owner's?

A popular method is also finding a seller who will finance part of your purchase (seller "carryback".)
