His entire post outlines things that I know to be true from my experience as a CPA.

You provide a basic outline of a plan most investors can use to create a 7 or 8 figure net worth.  

If I were you I would sit down with a notebook and outline 1, 3, 5, and 10 year real estate goals and get very specific about what type of property you want to pursue and how many deals you want each year etc etc.

If you decide to allow pets and then make sure your property is actually pet friendly as far as the types of flooring, furniture, amenities you offer and have a strict RA in place outlining what is expected I think going pet friendly could be to your benefit.

A real estate attorney can assist with drafting a partnership agreement that outlines the rights and responsibilities of each party and addresses any potential contingencies.

@Jay HinrichsHere is a quick outline.

It's crucial to have a well-drafted contract that clearly outlines the scope of work, timelines, payment terms, and any other pertinent details.

EVERY time an investor becomes part of our database, they can not enter without having signed our very specific disclosure that outlines the criteria of the transaction and what to expect(I don't see you in our database so your not familiar with this and should not be receiving our opportunities). 

First, clearly outline your short and long-term objectives, evaluate your financial preparedness, and explore different investment opportunities.
