I could barely proof it because it was so long haha

I also include the proof of the payments I made on the property and the IRS seems to not be annoyed by this.2.

I have docs etc if you are interested in verification and proof that I have dealt with that company.It is so unfortunate that I have to follow up what @Stylianos Kalamaras wrote concerning Blue Gate Capital.

Your lease should state something about quiet enjoyment and not disturbing others in which case they are in violation of the lease, so once you have proof, you can start an eviction (if your local rules make it hard to simply not renew the lease).Most cities have noise ordinances, so even if you didn't have quiet enjoyment in your lease, the city will have quiet hours.

Not bulletproof proof, but it helps!

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.

The seller can pay for it at closing (the title agent will cut the check to the trade to ensure there is no resulting lien) and provide proof of the replacement to the insurance provider.  

Most lenders require proof of someone else paying the note for around 9-12 months so that the debt isn't counted in their DTI calculation.

I have 0 experience ground up construction loan program nationwide that does NOT require GC to sign anything, only provide proof of 3 C/O's (certificate of occupancy) over the last year I.e. built received occupancy permission now unit is on market or habitable. 700+ FICO I can get you 80%LTC loan to cost on the project on ground up construction for 1-4 units.

FHA gets a bad rap because sellers and many agents think it's only for people who don't have the money so if I had 20 percent, but wanted to use FHA, I would present a proof of funds with my offer showing I have more money, but am using the FHA as a financial option so I can get an investment property as well somewhere else.
