Points On Loan for rental calculator (or any other advise!)

[Keith Manchester]

Hello! I have so many questions on how to properly fill out the calculators. Since my current plan is to buy a house and move in, fix up a few things and rent out I've been using the rental calculator. I can fill it out correctly until  I get to the "points". I think i understand that the points mean but can anyone delve in deeper? Any strategy on how many points i should get or use or not use?? Any info would be greatly appreciated. I will be looking to buy in Antelope Valley (Lancaster, Palmdale) area in the low 200s.
