I have been looking at properties and it seemed like the seller s  based their price on zero percent cash flow for the buyer.

Dont know where to start any suggestions will be great thank you For the 300k property they are probably not going to let you pull any money out based on the amount of credit you already owe.

I recommend that you find a trusted or recommended Mortgage Loan Originator (MLO), who can give you options for property-based loans (mostly investment loans) and they don't use your taxes but the P&L of the property.

One I know is based in LA as that's a huge market of course..

Following - I'm based in California 

The drop and Swap is about all we use here due to the confiscatory tax rates based on sale price.

Private Money Lenders (PML): More flexible, relationship-based funding with lower fees.

the gentlemen I fund finds them does the due diligence and I verify based on my years of experience at development.. but keep in mind these have some risk of failure thats one reason the returns are so high..

Since I'm based in Tampa, I don't look outside and compare markets. 

Are you basing this solely on what you can afford, or what you intend to make on it, or your target sale price?
