Where I think your argument goes off the rails is wanting the seller to subsidize improvements you want to make.

Unfortunately, most sellers are pricing these properties as if they are currently rented.Try to focus only on motivated sellers.  

I have an interested seller which i'd like to put under contract. 

The only way I would remotely consider it is if they were willing to provide seller financing. 

& Buyers (Crypto Holders) are responsible for volatile currency that will cost a premium but will be instantly converted into cash.Middle man, in this case a broker/realtor cashes in on premiums from seller before the home is even listed.

It is a seller market, it is hard to find a nice place.

Are Estate managers considered motivated sellers.

They'll be responsible for all the damages caused by the guests and even take care of minor repairs#3 Offered to sell your house to any prospective buyers using creative financing  ways like seller financing with minimal down payment and then selling that note and cashing it. 

Currently I have a motivated seller that needs to sell fast.
