I definitely appreciate your analytical approach....I think the main source of disagreement and confusion in this thread is the notion that you can pay off debt quicker if it's in a HELOC vs. an amortized loan, assuming you're not making any prepayments.

Sources of investment propertys and yhield based upon a buy and hold strategy,I hope you can help me.Wow,Its been a while since I have been back home haha2+ years now lolIts too expensive IMO and many folks are buying high and hoping to sell higher.Hoping a property will go up in value is not a strategy.

Just search and try to find ones that understand sourcing investment properties.

The only source for all the local information needed is an experienced local team.

The purpose of investing in a syndication is to leverage the sponsor's time, expertise and ability to source great deals, but if the experience is going to cause you to lose sleep at night, the return may not be worth it.
