It sounds like you're in a very advantageous situation with only $500 payment towards housing expense and saving $3k/month.

If you really need someone to walk you through it then maybe find a private coach who works directly with you and tailors their advice to your situation. 

Talk to a CPA regarding your specific situation to determine if income is passive or earned (active). 

If it was worth substantially more than $20k, there would likely have been multiple offers and the ability to make them compete and bid over asking.

I have helped clients in your exact situation in the last few weeks.You do not have to refinance that loan to purchase another home.In fact, you can purchase a new single-family home with 5% down and turn your current home into a rental.You can even use the rental income you will get from your current home to help you qualify on the purchase of the new one!

No, but it's worth my sanity and not having to deal with the big water bill situation you're dealing with now.

Also, if it's in an HOA, you need to find out the dues so that they don't put a lien for nonpayment. the risk in a situation like this is the lot is not buildable for various reasons and the owners just let it go to tax's.. the time to find all this out what before you bid.  

Remedial Action must be started within 24 or 72 hours depending on the situation and repairs must be completed within a reasonable period of time.    5. 

You need to call as well and multiple times and rotate lists every 1-2 months and call again.

It helps to have a conversation with a lender in advance (if you are serious...don't waste anyones time) to explain your situation and see if there are any red flags.For single family or 4 units and under a pre approval is also not needed but does go along way.
