Its always good to hear what they have to say but to ask for a letter will be a difficult ask as the landlord has no motivation to provide this.

Being a wholeslaer is having a business.You are in the business of finding and buying land/contracts for a short duration and then immediately selling them.One typical expense for a wholesaler is all the advertising costs to find motivated sellers.

You need to find a motivated seller that you can pitch to.

Example- finding motivated seller.

If this is me I am bringing them numbers (sellers that are not super motivated always state..

I am motivated and excited to learn, mingle and get to know some of you.

Glad you are a motivated investor willing to take action towards aggressively building your rental portfolio!
