I'm trying to figure out a strategy on buying real estate from the seller (no lenders involved) on payments, adding value and reselling it for profit and thus, paying off the original seller.

I have been finding tenants thru Facebook marketplace, been lucky so far, but I’m plan to buy more properties and manage them myself, how do I find and screen them more professionally without paying anyone

Most of the units I owned have room partners so they pay rent by their own individual bank ACH.

Give them the bill for the repairs BEFORE it is repaired and see if they pay it.

We got it ready to rent and although we had many many people inquire, they didn’t want to pay the price we posted.

According to the agreement, she is also supposed to pay a penalty of $200 ($50 fine + $150 for $10 per day).

Once they are stabilized, he refinances at 75% LTV to pay back the investors and have extra capital for the next deal. 

If you're seeking off-market deals and ok paying an assignment fee, checking out investorlift.com.

If you were to do a cash out refinance after the property is completed and take out that equity, you could pay off the heloc and lock in a lower long term rate on the home.

This gives you the dry powder you need if a good deal comes along or unexpected expenses and you keep the existing low mortgage rates and do not increase your payment until you use the HELOC.Consider how you could increase the cash flow on the existing properties and if you have the means to pay off one of the houses to increase the monthly cash flow that way.
