Dan before you worry about the condition of the properties you're going to want to narrow down the locations you are comfortable with 1st.

There will be less options when you narrow your search down in this manner but you may be able to find exactly what you're looking for.

That being said, if you narrow your search to a specific type of house in a particular area...you can get some general purchase price numbers.For example, I am looking in a specific area that has tons of 1960's houses and the home values are all right around 220-240. 75% of $240k is $180,000, so if I can buy a property and be at or under $180,000 after acquisition, holding, rehab, financing costs, etc then I can pull all of my money out. 

You just need to narrow down what type of neighborhood and tenant you are going for.

Lots of things to weigh out - Her present health condition and needs can really help narrow down what is best for her.

@Julio CorderoHave you narrowed down the properties you are planning on investing in?

I still work a FT job so I feel trying to narrow down to better quality leads would help my time management...Thoughts?

Most investors don't pull out 100% of cash invested most of the time.Having a narrow business model like Jason can work if you get enough deal flow. 

Including these estimates in the listing could help narrow down the buyers to people less likely to walk away mid deal.Good luck. 

There are a lot of options available but I am not sure how to narrow down my search.
