Can they prove how long it takes to rent a vacant property?

The other is unrelated and we suspect is tied to the tenant (who was with us for 3 years) that did not renew their lease and moved (we cannot prove this).Again, many thanks!  

Of course, he is free to come here and prove me wrong.

I've had a long career in community development and have a lot of bank contacts that would likely be interested in investing, but I'd need to prove the concept first with an initial fund (there are also a lot of other community development tools that could be leveraged to maximize and scale this).

I proved to them lending me their money was an easy way for them to profit themselves.

I do generally agree that once someone has their person, they are not going to be very open to switching. but if you can prove yourself with someone building that team, you may find yourself in a great position. 

It’s about proving you can return their investment.

Keep detailed records of your hours and tasks—it’s crucial for proving active status if ever questioned.Don’t overthink starting with Airbnb/VRBO.

I've heard that some people have used a trust account or something similar as a method of income, if you can prove history of payments and continuation of these payments.

You have to prove you did everything right and then because of “empathy” for the poor snook who “fell into you schemes” you may lose anyway.This is a legally binding transaction that will be treated that way by the law.
