I value my reputation with brokers and don't want to consistently back out of contracts if I can make a reasonable evaluation prior to going into contract.  

Be consistent and it will take you far. 

The average person’s attention span is almost no better than that of a flies so if you want people to read your posts you have to make them engaging and interesting enough that people will want to read your stuff consistently.

Consistency is going to land you your deal. 

But I'm trying to find the market that will consistently give me the highest rents in decent neighborhoods for around 120k all-in.

Where is this consistent flow coming from?

You won’t always catch a dramatic market rise if you consistently do this, however, when you do, you can turn that ‘3’ into a ‘6’ or more!

According to the Engineered Wood Association, a one-hour rating indicates that a wall constructed in a manner similar to the one tested will contain flames and high temperatures, and support its full load, for at least one hour after the fire begins.MaterialsAccording to the book "Commercial Drafting and Detailing," a typical one-hour fire rated wall consists of 2x4 studs spaced 16 inches from the center of one stud to the center of the next, covered by 5/8-inch, type X gypsum board.

If you are consistent with learning real estate over the next 4-6 months, you’ll be ready to purchase your first (or next) property in NO TIME!

@Austin WoodThere is also another method, that my work.If the property is in a really strong neighborhood with a history of consistent appreciation, say 7%, you can hold it for 10 years and sell at that time. 230K Value Now = $452K value in 10 years @7% appreciation.Clearly will only work in a neighborhood that has that history, otherwise it's flipping coins.
