However what I can do is build a whole new house attached to the existing home that would be completely its own entity but it can only be a single family.

Today exists another opportunity that only the enlightened few will be able to take advantage of.

I'm not aware of the existence of those stats.

There are following const involved:City or County fee per EDUEngineer Fee (if applicable)Labor + Materials for the pipe installationDo you need to install only the latter line and connect existing pipes to it?

Most would want to take out the existing first positions though.Are you looking to buy all cash in the new markets or use the funds as down payments securing new loans in the new markets? 

My funds are non existent currently, which is my bane. 

I have been bidding on real estate auction for years and done well, here are some suggestions that may help you:Here are some things to consider when attending an auction - helpful hints.Preview properties with an auction associate if possible.Make a pre-auction offer(to avoid the competition).Ask for known details (zoning, tenancy, existing financing, code violations, taxes, comparable sale info/comps, will seller finance?)

I'll have to run different scenarios, ideally I'd like to move in, complete small needed repairs to retain its value without making any significant upgrades, rent the property out and make sure it flowed before going that route.  

That credit score where the break even exists is roughly around 680 - 700 fico.

@John Suralik  subject too is a very old and easy method of acquiring RE its not big deal. what it is is uber risky for sellers unless the sellers have already lost their credit and don't care and are walking.. the reason is you take Title subject too  the existing loan.. remember loans stay in place unless paid off and even though all debt instruments have alienation clauses they are rarely envoked.
