I will need to finance most of the purchase, but if my numbers are correct, it would still generate cash flow even with 100% financing.

Your other option is to pay cash instead.

Say I pay cash for a house or put down 30k?

That will vary depending upon your experience level, the quality of the property, the cash flow of the property, and the lender's appetite for that type of loan.

I did overpay for the property, but not to where I am screwed if I where to move out right and get it full rented I will cash flow about 50 dollars per door so it is very slim margins 

I am trying to see if a home has an exterior shut off for electrical --- this is all I found.

My current strategy is to maximise equity over cash. 

Also did you grow only through cash flow or did you take investor capital to reach where you are today? 

Even with conventional loans, unless you've been self-employed less than two years or don't report your income, it's the same as someone with W-2 employment We lenders just cash-flow you differently.

And if you are handling the bookings/marketing, get ready for constant calls from the owner that over leveraged themselves thinking this is a cash flow market when, at current prices/rates it is not, unless they invest significant capital into theming.It's great that you've found a handyman/cleaner you trust.
