It’s really crappy for them to leave a negative review after you refunded their entire stay.  

The other risk of heloc is that is a recourse loan versus mortgage is non-recourse loan and the  situation of what happened in the 2008 fiesta were heloc were getting frozed by banks since house started to get negative equity, so can that situation come with heloc on Primary and Vacation homes.I have been trying several community banks and no one seems to offer heloc on Investment rental property but they offer a Commercial Business line of credit secured by the rental investment property, how does that work?

They carry a negative connotation of poor white trash from some scenario in the 1950s.

When these alemployees approach me it's always in a very aggressive and negative and sometime threatening fashion.

The 250 hour rule is the Safe Harbor, which is negated if you qualify as a Trade or Business (as @Natalie Kolodij originally mentioned).I'm really glad you're going to an accountant. 

Depending on if you itemize your taxes or not and if you can afford to be cashflow negative you may want to try for a shorter loan. 

looking for advice for crowdfunding, i am currently looking into investing in crowdfunding real estate to build capitol for my first rental property, this seems like a good option for me since a lot of the websites offer you to start with a $5000 investment with a 7% return on your investment. if anyone has done this before and has had a positive or negative experience please share!

They have some great ball park statistics with sources including places like the U.S.

Just remember: most negative reviews are written by problematic tenants.

I don't buy negative cash flowing properties, the numbers work and they are safe, but I expect appreciation in the long run.
