All are 3bed 2bath and close to 300k range. which external factors should I consider to finally choose my home(appreciation & rental potential)?

In the course, we were told Non-Performing sold in the 55-62 cents range.

So instead of dealing with a project way under his profit range, he finds his best employee and sells it for $15k and uses it as a write off.

BrieTo give you a snapshot of DSCR lending right now, a cash out, 30 year fixed to 75% ltv with a couple of points (depending on the loan size and a 4 year prepay) is in the high 4% range with a DSCR loan; no balloon or ARM and no LLC required. 

Your ARV should be an actual (conservative in my opinion) number, not a range.

Assuming there is sufficient equity, which he would need anyway if he’s getting the heloc on the same property, he could just cash out refinance now and skip the heloc, if he wanted. 

It depends on your portfolio's characteristics (and your credit score, liquidity) but the typical range is about 4.75% - 5.5% for a 30 yr fixed, with a 5 year prepayment penalty (if prepayment penalties are allowed in your state -- some states, like OH, MI, PA have restrictions on prepayment penalty terms & fees).

They're typically priced in the 4-7% ranges so they're not going to give you that ultra low 3's rates that a conventional lender might.It would be best to figure out what your scenario is currently and see which route would be best for you going forward. 

@Mike Bianchi you could buy fully renovated 12+ unit multifamily in OKC for that price range.

Fridges, ranges, HVAC, roof leaks, repaint and carpets at turnover, landscaping during vacancy, clogged toilet, etc: these things happen.
