I would approach it as a math problem:1).

@Alec Saenz,Check the local government tax assesor's website to see if you can find out more information about the property, maybe even the owner's name.If you can get the owner information, you can take the approach of sending a handwritten letter asking the owner if he/she is willing to sell the house. 

How do you approach a house you’re going to live in.We are getting ready to bid on a property that instead of renting we are thinking about living in for a few year (5-7).It will be a rental till my husband retires form the military (2 yr) and then may become a rental if we move on.The house is in a good location.The neighborhood is older, but the homes are being revived.

@Ryan Toth  my arrival to Charleston was quite by accident but it did not take a 2 by four to the head to figure out what was going on.I was first approached with doing 4  fix and flip short term loans.. form one of my very OLD time clients of 15 years..

But we've approached a wealthy friend who is very interested in being our bank to secure good lien deals.

I'm going to practice your "finding people behind on their taxes approach. 

@John HixonThanks for the kind words@Mark KvamThe following people I think should be consulted regarding your mobile home park purchase@John Fedro@Curt Smith@Ken RishelMaster lease options in general is where we "guaranteeing the net operating income NOI" on a master lease, have an option to purchase based on NOI, and then turning around the investmentAll leases are turned over to you as a master tenant and you in turn sublease  outThink of a poorly managed apartment building, with a low NOIYou increase rents over time and decrease expenses and efficiency of managementWith a master lease option, you can sell your option or exercise your optionMobile home park negotiations, I would think that that's a late sale and purchase agreement with a large down payment would be the most prudent way to approach it, you may need private money to execute the  sale and purchase agreement@Bill GulleyMight have a few ideas too

There are two approaches most commonly referenced on the forums:a) Cash for keysb) Eviction

Can I approach a (different) bank and ask for a home equity, without disturbing the current mortgage (since I did a quit-claim)?  

As you've probably started to see, flipping houses and owning/managing rental properties are two very different approaches to investing in real estate.
