Donald Cressey is The Fraud Triangle: 1- A perceived unshareable financial need. 2- Perceived opportunity. 3- Rationalization.Financial pressures change in life, medical care for aging parents, a family member becomes ill, college costs, mid-life crisis, substance addictions and gambling, jealousy/feeling "owed" or wronged, social pressures to "get ahead"...The biggest losses are always where there are no checks & balances, no separation of duties, no policies and procedures in place. 

Fraudulent (as some posts suggest)?

As more and more tourist income comes from non-gaming activities at least it's less dependent on gambling.  

This means you can't have a balloon payment though unless you are willing to gamble on appreciation.2nd, you could make an offer for 250 with a clause saying that the seller will get their other 50 when you sell the property, or some variation on this.  

Appreciation is gambling, but sometime “the house” doesn’t always win.

When you are gambling a huge factor in your success is limiting your downside risk.

Those who have had experience, were there signs at the beginning that you may not have chosen a good tenant, or is it a complete gamble and you just don't know what you're going to get.  

The salesman made many fraudulent promises and he did not tell me that the timeshare was for one week one year and two weeks the next year.

Properties that are unique in their neighborhood are notoriously difficult to calculate for accurate investment value.Do you want to be left stranded, committed to buy at a price the Seller already thinks is the best net-price they can get, and you would be gambling it wasn't?

Similarly, if you're the riverboat gambling type, you can try looking into an equity deal where the buyer pays you X% of final sales price and/or a percentage of rental income if buy & hold.
