If there isn't one website or source, what is another method other than looking at the competitors?

I started with the BRRRR method for long term rentals.

They have been consistently late on payments (we’ve emailed them twice about it), they broke the lease regarding having extra dogs/cats and started a boarding business in our home which we informed them was not allowed as soon as we found out, as well as lacking in communication with them regarding things we needed to fix around the home.This is in California.We’ve just wanted to see what our next steps could/should be.

If mom and pop did poor marketing and you bring in professional-grade internet SEO and other methods you could theoretically double your revenue in one year without any additional cap-x.

His communication with me is terrible.

A house that cheap is going to be difficult to finance with traditional methods.

One thing I will also mention is that there is a communication flow to managing them that is much different than a normal rental. 

Now that my backstory is out of the way..What are pros & cons to using this "creative" method to finance the property?

I wound up putting an offer on a house in Indianapolis after communicating with several knowledgable people including a great realtor and other investors.

What bothers me about the GC method of purchase is the buy it for whatever price and sell it for more later no matter what model.
