You likely can't tap into your equity without selling your property currently due to your credit and being in an active bankruptcy.

I have a duplex I recently purchased for cash using a line of credit. 

Consider a HELOC a credit card secured by R/E.  

My credit score is in the mid 700s.  

Finance of America offers a line of credit for flipping that is based on a multiplier (5x I believe) of retirement and savings.

We respond with an email outlining our standards-you know; income = 4x rent, credit rating 700 etc.

Johnathon contrary to popular belief HML these days post GFC is just about as stringent as bank financing.you NEED money you NEED credit and you NEED experience.best way to start is to partner with someone who has the above and build your own experience bucket.you will not get a loan with the situation you described.

If, B: The seals are bad, replace them because this will then be a selling point, but go for the less expensive option because you have the nicer house on the street... putting more money into making it even more nicerer will be a waste... if that makes sense.Another option would be to say that you're giving the buyer an 8k credit towards windows of their choice (or they can pocket the money if they don't want to change them). 

You can borrow from bank (signature or Home Equity) private money, hard money or even put on a credit card.Then you wouldn't have to worry about the pool liability or tenants.Maybe your In-laws would front the money?

Credit cards, student loans, plain ole vanilla mortgages, etc. because they have somehow managed to mess all of these up at one time or another.
