The hard money loan is a temporary loan and at a high rate. 

Emotionally detach from the property.

The problem with that analysis is that most investors get too emotional with the home just like the average home seller.

This could be due to a temporary glitch, planned site maintenance or perhaps BiggerPockets is just too busy right now.

They had cash, and were really not up to dealing with anything at all emotionally.

Some times there is an emotional attachment, and they cant set foot in the house again ("mom died in that house", etc).

Since you are buying a holding properties the item I would caution you on is that Lines of Credit (LOC) are for temporary money. 

Unless you are looking for a future retirement home for yourself, try not to let emotion drive your decisions. 

If you have a source of temporary private funding, you should be able to get a mortgage later, so long as it meets all of the standards of the lender (i.e. adequate appraisal, no title issues, etc.)

Not emotional - just as an investment.
