Purchasing a House all Cash Then Refinancing

[Neil P.]

I would like some expertise on this current issue I'm facing.

I have this house 155,000 purchase price.  I want to do all cash and refinance.

I am going to get an appraisal done Monday, the seller is very confident the appraisal will come out to 200k or above.

Lets say it comes out to 200K, as soon as i close the house i want to refinance the home.

The bank that im using is saying they will give me back 75% of the appraised value.

So say i put 155,000K cash in.

Appraised value 200,000.

Bank gives back 75% of money= 150,000 back.

So in essence i get this house for 5,000 down cash.  

How can i lose here?  What am i missing?  I feel like this is a deal to good to be true.

I have 1 investment home, this will be my second, so im pretty new to this.

Also the appraisal for the house will be the same appraiser the bank will be using when i refinance.

This property is in NJ, i will be holding this property its a 2 family home.
