Hi Jourdan,
It is certainly not unheard of, but in my opinion, unnecessary to show you mean business. All you need as proof of that is to write a well-thought offer and have proof of funds to back it up.
From what you say, I can't tell if you are a real estate agent, but if not, my next advice would be to work with an agent to represent you and advocate for you during the transaction. They can write the offer for you and ensure that your offer is taken seriously.
Now, I'm not saying you can't make an offer yourself. All I'm saying is that having representation with your best interest in mind is a good way to go about when buying real estate.
If you need to find an agent in your area, you can:
1) Use the bigger pockets tool to find an agent.
2) Ask around the forums, and they will offer their services.
3) Send me a DM, and I can recommend one.
No, I'm not an agent. Not yet anyway. I've taken the course and am studying for the exam.
I am working with a very good agent.
In all my networking a few investors that are doing very well used this strategy to stand out on their first partnership together and I was thinking of trying the same method. Just trying to figure out the best way to go about it.
