I made an offer on the home and it has been accepted. 

Is there any banks offering a HELOC on a rental property?

There was no hesitation on our part... we own 37 doors (bought between 2018-2021) and managing our real estate is our full time job; but I want to offer you a corollary as to your "why does everyone wait" question... which is to say, "Maybe SOMETIMES they should be waiting..."  

I aim to have it show the impact of K1 losses if the syndication offers it, and that tool is helpful because some of the comparisons will show a real estate syndication vs mortgage notes or debt funds that may not offer the same tax advantages/losses.I've included some of the criteria I was putting on the Excel calculation below.

Ben, I own a lending company that offers loans for investors.

The city offers a strong rental market and with affordability as well as a median home price below the national average, the city stands out as an attractive option.

I'd offer a discount for those who stay longer (eg weekly rate that is slightly less than 7 days). 

@Tim Silvers ask your title company if they offer an enhanced policy.

Every system you try will have flaws, or you may salivate over a feature that appears in other software.Some familiar names are mentioned frequently: Stessa, Apartments.com, RentRedi, TenantCloud, Innago, RentManager, Avail, Rentec Direct, Doorloop, etc.I recommend conducting thorough research on each app online to understand their offerings, pricing, etc.

Over 10 is when you need to do a security offering of some type.
