I'm always amazed at how people try to get lenders/financial institutions to change the rules to fit their situation instead of changing their situation to fit the rules (Again, making no assumptions the OP or anyone else fits that declaration).Scammers love "subject to" because the scammers only have an upside potential and no downside because they have no skin in the game (Outside of maybe reinstating a defaulted loan) and, no liability for being wrong. 

But this is a public internet forum, so toughen your skin and ignore the haters and embrace the good advice. 

CA just skins alive high income people with the highest state income tax in the U.S.

Even if they don't appreciate it's no skin off your back. 

I understand that you have more skin in the game then most as you have intellectual property and credibility on the line and must defend what you are passionate about.

Giving mortgages to those with little skin in the game or marginal credit is the same.  

@Mike Alder   you may want to look on E bay for used course material from any of the guru courses the information is all the same there is only so many ways to skin the RE cat  as it were.

The second is that they expect you to take at least a 30% or so equity position in the property so you have "skin in the game".I wanted to know if it is possible to get a mortgage for more than 70% if the property looks like it has better than average earning potential, or if that is a hard and fast rule.Thanks!

It has taken some thick skin and a complete disassociation from reality though to get through the stress of limited reserves but I’m back!

Talk about having skin in the game.
