Any guidance or tips would be greatly appreciated!

They are running a personal brand, and I would rather donate my money to a good cause than their next mountain home. 

I'm struggling because the first 3 homes I bought were homerun off market deals 3-4 years ago w/ great cash flow and appreciation. 

The home was then sold for a profit, providing a strong return on investment.

This will be my first home purchase, and I am aiming to invest in multi-family properties.What should I be aware of when purchasing a multi-family property?

I've helped dozens of tenants become home owners through lease options.

When I spoke with a real estate professional, she said the home would probably sell for around $250k in its current condition.

What are some key tips and websites that you know about that I can use in terms of RE Financing?

I've seen some people house hack a single family home by renting out the rooms, but keep in mind that traditional lenders would not be able to use the income from renting out the rooms (known as boarder income) towards additional income on the application.

Taxes are a lot higher on rental homes.
