Do the rehab, place renter and refinace when you are finished. DON'T, DON'T, DON'T take all the equity out when you re-finance. Stick to the rule of 70% (or even 65%), which is to maintain 30% (or 35%) equity at all times. This rule keeps you safe in slow markets and allows you to have multiple exit strategies. It allows you to sell at a discount if needed and still make money.
If you don't have the money, then you will need to do HardMoney or a standard re-fi. If the house is in bad shape, you may need to do some work BEFORE trying to cash out re-fi. Why? Because banks don't want to get stuck holding the back on a shitty house if you take the money to Las Vegas instead of putting it into the property. You may also look at doing a construction or rehab loan. What is your credit like?
If comparable properties are worth $70,000, then you should never be into this property or more than $49,000.
That means the most you should re-fi for is $49,000. You have not talked about rental rates. How much are they?
