Plus, he said let the tenant go to court as burden of proof is on him.

With no proof required.  

Definitely do what it takes to add some sound proofing.  

Proof of concept seems to be a key part of your strategy starting off.   

I presented unrefutable proof that I was right and my comps were solid and that they should change theirs and let the deal go through.  

We've been head down for 5 years getting started with this portfolio, just starting to become an evangelist for sober living now that there's some proof in our business that it's impactful and profitable.

Tenants like to set up insurance, show proof to the Landlord, and then immediately cancel the policy after moving in.

On the other hand, I’m hesitant to simply pay down more of a property, as we don’t need the immediate cash flow.Fortunately, both my wife’s job and mine are recession-proof, which allows us to be a bit more aggressive with our investments.I’d really appreciate advice from investors who have experience with frequent moves or military service.

As for submitting an LOI without proof of funds, sellers may still consider it if you present a well-researched offer, highlight your experienced team, and provide a clear financing plan.

Provide them proof of your ability to find, fix, flip (or whatever strategy you plan to use), and then start with small amounts of their money.
