My biggest fear: no matter what safety measures you take, if a renter's kid or neighbor kid drowns, somehow it will be your fault.

I agree with almost all of it.What I am missing, and not just because it is the start of a new year, is the focus on goal/purpose and the way to measure progress.You said you want to buy and sell properties and worry about the price.

As wholesalers, do you measure "customer acquisition cost", where the customer is the seller.

If you see cracks, have the foundation inspected by a professional to assess the problem, especially if they measure more than three-sixteenths of an inch.

There is no property appraiser website, what you are referring to is the assessor’s office which accesses property values for property tax purposes only, they are not accurate measures of current market value.

Based on any measurable data, this is D territory at best. 

Without tax returns or operating statements I don't see how this will get financed unless you have access to private money.This is a cash deal, and if it's on septic will have about a 50% expense ratio with proper management (I never use the Sellers expenses as a measure).  250k is very high for this property unless you're in a metro commanding 6-8 cap for MHP's.

One of my Real Estate instructors (who has achieved a certain measure of success), once said that the trick to buying raw land was in determining which way the city was growing.

We have to use the same rule the contractors use when hiring, "Measure twice, Cut Once!"

For a newbie, doing ceramic/porcelain tile oneself could take a very long time I assume, with the inevitable measurement mistakes, do-overs, etc.How much money do you save by doing tile (or flooring in general) by yourself?
