Yes, it is a paid product, but it is worth every penny.

I have had to take my rentals out of my LLC's to acquire a second on one rental and a HELOC on another. 

HELOCs are very much a short term product, because the interest rates can go up precipitously, they have been called due in past credit crisis situations.  

You should definitely check out Avery Carl's BiggerPockets book "Short-Term Rental, Long-Term Wealth" https://store.biggerpockets.com/products/short-term-rental-l...There is a lot of amazing insight into everything to think of while operating an STR.

@Courtney HamiltonI have found that my rental listings are no longer Auto pushed to Zillow even though Zillow generates by far the most traffic for a rental listing almost 70% of the leads are from ZillowWhen you do your market analysis I would highly recommend pricing your property $50 below your competition because best products and best price equals the best tenant.

They may require you to use their services, but they may not be as picky about whether the plan was their production or not.

George Washington acquired a significant amount of land this way, and shortly after acquiring such created SYNDICATIONS (he later used JOINT STOCK COMPANIES when they came into existence) to raise the capital needed for development.  

I have a 2 bedroom 1 bath in highly sought after Judson Mill area of downtown Greenville, but haven't decided what I'm doing with it yet as I have several other projects going on right now.Most of my rental portfolio has been acquired from tax lien sales.

It's not the cheapest yet their price were not that much more than their competitors and SIW was a better product.

If I acquire the second property with full cash, that's at least an instant equity which I may be able to tap into for 3rd, 4th,..assuming properties rise in value over time.
