You are interested in a certain market to use the BRRRR (Buy, Rehab, Rent, Refinance, and Repeat) method to purchase property.To find these properties, you asked how many Realtors you would contact in that area.Honestly, most Realtors do not speak investor language and are not investors themselves.

Add the financing challenges and that you existing structure likely will become rent controlled.  

I'd send out 500 at a time, using a different mailer/method weekly.

You could also structure a plan that has the income snowball pay for the coaching fee.

Used houses in the area sell anywhere from $75-125 a square foot.These are long term rentals that I do not plan to sell.I am reading the Rental Property Investing book and implementing the method that focuses on cash flow and that strategy states you need to have $300 cash flow per month, per property.

And if this LLC structure is overkill than what are the alternatives?

As far as whether to approach them with or without an agent - approaching them directly without an agent can save the seller probably 2.5-3% of fees, which give you some room to negotiate on the price, but you need to be confident that you are capable of evaluating the property value, estimating on the amount of work that is needed, knowing how to negotiate/ structure the deal, and navigating the closing process.

Raising money is all about marketing and sales (not real estate specific) so either hire marketing agency and read sales books, or hop on some LinkedIn courses on marketing and sales.Not sure the legal structure to use: talk to accountants and attorneys.Need deal flow: talk to brokers and go to a lot of networking events.Lending terms: start calling banks and loan brokers.From there, it is all risk mitigation. 

Curious as to the draw fee amounts you all have seen that have deterred you from wanting to pursue that method. 

I have deals needing funding and want to ensure I'm structuring them in a way that's competitive and appealing to private lenders.
