Hi Trever,
I would say if you have access to the county courts records (tax records) and can look at the properties kind of close to you then you can determine what kind of homes are in your area, "A" "B" etc. then see if you would like to invest in the ones that are maybe in the "B" type.
One sure thing that works is a "B" type that is about 2% of purchase price I have heard is a sure way to make sure you make money. ( but is hard to find in that "B" area.)
0) Try contacting owners that do not live in the property to see if they want to sell these are great properties to work deals on.
1) Working with an agent you might have to interview a bunch that knows the area you want to buy in and they will have a wealth of information about the area and you can decide and make offers and the agent will have to do the negotiating you just tell them what you have to spend all in.
2) Ask around to see if you know someone who wll make a good tenant if you want to buy a buy and hold income property. You may have a very good part of your questions answered if you just ask around. This can go for the property you want to buy as well.
Well hope this helps
