BRRRR is a method not really a business template (if such a thing exists for any business). 

In my experience trying to raise capital from people within the real estate community doesn't seem to be the best method because most people in real estate are more interested in building their own businesses, rather than investing in someone elses (especially when considering how much money it takes to invest in syndications).

I know there are investment platforms where sponsors can connect with investors, often at a premium, but I’m curious about other proven methods that don’t involve purchasing a list of accredited investors.For those of you who have successfully raised capital, what approaches have worked best for you?

I personally don't agree with the cost per square foot method, way to vague and inaccurate.

I like to purchase turnkey and use the house hack method.

The most efficient method  is to create one contract and then add/subtract properties that are either acquired or sold by this particular client through a contract addendum. 

I have been successful having my insurance on my personal home AND my STRs lowered with this method. 

This allows you to deduct the full cost in the year it was placed in service.Fences are not eligible for the Section 179 deduction as they are considered land improvements.Given this information, you have two main options: 1) Take advantage of bonus depreciation (if eligible) and deduct the full $4,200 in the year the fence was installed.2) Depreciate the fence over 15 years using the appropriate depreciation method (likely GDS).To ensure you're making the best choice for your specific situation, I recommend consulting with a tax professional who can review all aspects of your rental property finances and advise you on the most beneficial approach.Please feel free to reach out if I can be of any help.Best,Jackson

Rabbu has my market at about 50% of what it should be for instance.But I think between using all the tools, talking to STR friendly realtors, the enemy method, etc.....one can get fairly close
