TIA for any guidance and considerations.  1)  I'm having difficulty finding a HELOC amortization calculator. 

It's incredible how much valuable insight comes from the BiggerPockets community, and I really appreciate it.

I read a bunch of the guidance online but I can't tell exactly how the property is classified once this has been done.

Exceptionally rare, highly valuable. 

Is there any reference I can consult for guidance on these issues?

I appreciate everyones time & guidance!

These are absolutely very valuable information to help me adjust my strategies!

As Mason points out, the more you do the more valuable the project. 

The more value add needed on a property the riskier it is, for your first deal I'd consider that when you're looking at this deal, if it's your first one a partner who has done something like this before could be very valuable. 

Obviously, a complete and well built website with interactive components and quality information that’s constantly update and optimized for particular keywords to show up on the first page of search engines (including YouTube) will bring in the MOST valuable leads.
