In real estate, it is really about your cash on cash return, so the least amount of money you put into the deal, the better.What would come out of pocket at that point would be the difference in down payment, which in this price range tends to be limited.

If I were to sell, I would look to buy another multi-unit property in a smaller town in the $100-120K range that cash flows $400.

They offer a range of options for monitoring vacant properties, including some handy sensors that attach to water heaters and alert you if water is detected in the drip pan.

I would be interested though in hearing about your connection with manufactured homes. 

Quote from @John Herold: Hello all, what are some best practices for LVP floor installation for a manufactured home on a permanent foundation?

Also, try to find similar rental units in the same neighborhood to compare to so you have more of a rent range/conservative approach. 

Antioch is a solid area to focus on for a very diverse range of deals. 

@Hector Espinosa While cap rates can vary widely from one market/city to another and from one type and class of property to another (and based on the quality of the tenant), I did a quick search on LoopNet for MF properties currently for sale in SD and most "asking prices" suggest cap rates in the 4%-5% range.

I think you'll find that's a unique range and won't have as much competition.

Look at buying my first investment property (probably a house in the 100-150k range) and begin looking for a tennant.I can imagine there a lot of different theories/ideas with what one could do here--I am just curious to see what other people think.
