Based on the numbers above, It looks like 27k down for a $329 per month positive cash flow after expenses. About $3800 a year return.
This does not, however, speak to a lot of the problems with this model. Memphis is among the leaders in the United States with the highest vacancy rates. Some of the others are in North Carolina (don't remember which cities, but there are 2 or 3 in NC). I think Indianapolis is another, but don't quote me. This can be problematic in attracting future tenants if the present tenant does not stay.
Btw, many of these TK companies are in these high vacancy cities. After all, you have to be able to get property on the cheap to make this model work. ;-)
From my own research, most of the TK properties at B or C class properties that are older than 20 or 30 years. That's what is required for that type of return that is stated. But older properties also have higher expenses and maintenance issues. Some of which can be large ticket items that wipe out a years worth (or more) of profit. Older properties in these low cost areas won't appreciate much when compared to better quality properties in better neighborhoods in the same city.
A loss of your renter could turn disastrous. It's not a -329 off the $3800 gain, but about $1000 a month. If your property is being turned yearly, you will lose about another $1000 for the real estate agent to place a new tenant in addition to cost of getting the property back to rentable condition.
Personally, I think it is a safe bet that an investor would be lucky to clear $2000. And I believe that would be a 'good' year. I think many other years would be 'alligator-like' with high maintenance costs.
But these TK companies are filling the need of getting people into real estate investing. I just don't think it will be a good experience for most over the long term (5+ years).
