Can somebody PLEASE give me tips how you negotiate a homeowner down? 

I’ve watched several videos on YouTube and many articles online as well.

So, about the numbers, I would take a look at the Tools section of BP where they are calculators for several different types of real estate investments, they also have some video tutorials on how to fill-in the numbers needed to run the calculation.

Are there any tips the community would suggest I go about, or avoid considering the details above?

Read and watch the videos. 

Apply all the tips above.
