.: @Colleen A LevittYou can always pay off or refinance the loan.

But once you pay attention, you can't not see it again. 

A lot of research and studies have come out around high paying jobs make large impacts. 

You're going to end up paying a lot more interest on a heloc than a 2nd mortgage, if you intend on holding that debt for more than a couple years. 

I am about to pay the land cash 500K, then build 10 apartments for roughly 1.5M.

You pay for the basement reno out of pocket and cash out immediately...instead of waiting for 6-12 months

They're paying for results.  

is it worth paying the $99.00 to list on furnished finder? 

So I proceeded to pay for four appraisals that were like $800 apiece.

You could also get a line of credit for about $150k (you should be able to borrow 75% of the value.)The reason I suggest this is…1) you save $40-$60k in selling costs. 2) you have a lower blended interest rate (2/3rds at 3.25% and 1/3rd at 7 or 8% instead of the whole $500k at 7 or 8%) saving you another $1k/mo in interest. 3) you only pay interest on that $150k when you actually use it, not from day 1  Unless you hate this property, or want to buy something you can’t afford without selling, that would be my plan.
