Later I found that I had some electrical problems that had not been uncovered.

How many people do you know that have bought a property to flip, and uncover a major problem that wasn't shown in the inspection?

Obviously getting a thorough inspection should uncover the likelihood of some repairs and provide somewhat of an estimate of the timeline for the major ones (HVAC, roofing, etc.).

It is important to be aware of these potential large uncovered losses when making your insurance decision. 

You'll most likely need to get out a shovel and uncover the entire drainage route for the water.

J:Modular building construction is far more common in Europe and other parts of the world than here in North America ... but still comprises <25% of new construction even in those places where readily available (to the best I've been able to uncover thus far).3D printing on the scale of buildings is still in its infancy, but interesting results are already being produced.  

Perhaps you could uncover some information about this topic by setting up a key word alert, which will send you an email any time someone within the BP community addresses the topic.  

I understand the concept of what I'm trying to do, it's just the details that I don't understand and what I'm trying to learn.Here is an example property on craigslist I thought seemed good: 4-plex (pictures and google maps shows that it is in a group of similar 4-plexes, like a small apartment community), asking $189,000Year Built 1981 Sq Footage 3,648 Bedrooms 8 Bathrooms 4 full, 0 partial Floors Unspecified Parking 4+ Uncovered spaces Lot Size 8,714 sqft HOA/Maint $0 per month I like the location allot, and from my time living around there I would say the rent is about $700 per unit, so $2,800 with all of them rented out.

Without exception, every episode of "Flip This House" that I've seen has a portion of the show in which almost immediately after purchasing the house and beginning the rehab, they uncover some sort of problem that they didn't budget for.

As tight as the leads are, you/we all have to build up our marketing capabilities to uncover off-market opportunities.Rick
