You'll lose that rate and your total monthly payment on this deal will skyrocket from what it is today.A HELOC comes with a variable rate that is generally tied to the Wall Street Journal prime rate.

Long vision yes things will go up BUT one will have to ride out the short and mid term variables and be accepting of such. 

@Scott MacFrom what I heard These allegedly were variable rate loans with no cap.Properties were allegedly purchased at a cap rate under 5 and the sponsors experience was allegedly questionable.

Multiple different variables for making this decision.

Another variable is the "impact fee" some (Most!)

I would like to use a HELOC as downpayment and rehab funds on properties between $50-120k, and then maintain my $25k liquid assets as emergency/operating funds for my deals.I have looked at getting a HELOC from Navy Federal Credit Union as they allow upto a 95% LTV on a variable rate HELOC.

@Ricki Joe Abney how did you arrive at your variable costs.

History would disagree with me, but history hasn't faced these sets of variables.

The return on adding solar to a rental property in my market is pathetic.There may be some market variability to the advantages of adding solar to a rental, but I suspect in virtually every market there are better investment options.

250$ would be good for a single family home .. the problem is you did not account for many of the variables and that 250 doesn’t really exist .
