Check the plumbing - I prefer to always run new hot/cold risers and laterals before you start renting, as it will never be an easier time and you can sleep well at night knowing there will be no calls from tenants about a water leak!

Enter new to home buying guy and wife looking to buy a home in San Antonio to live in then rent out.Home listed for $220k it was a flip and was purchased for $60k less than a year ago.Exterior looks wonderful, inside looks great.Original 100yr+ hardwood floors, everything looks very shiny.As we are walking around we start flipping switches, flushing toilets etc.One toilet in particular makes a very gurgly sound that doesn’t seem right and some hall lights don’t work.Our RE agent is all about telling us to hire a General Inspector which will cost about $400 to inspect the property and tell us if anything needs to be fixed.As we look around we start to see more problems.There is a place in the roof where the roof has raised away from the house leaving a sizeable hole to the attic.There is no drip edge along the roof.The breaker box has empty slots in it that let us see into the drywall.Knowing this was a flip we investigated on another Texas State website to look at all the filed permits for the new electrical, plumbing, HVAC, and roofing, and got nothing.No permits filed at that house.Red flag?

Since you say there are two doors underneath, a possibility (assuming this structure is level with the rim joist) is to slot the rim joist and cantilever 12-16' 2x8 or 2x10s to take the point load at the house, and then locate the outer beams properly.

@Deb Merrill I would probably go with natural gas forced hot air.

But, the market will tell you what's hot and what's not. :)   

Rents are at near market rent, but includes heat and hot water.  

Recent post by @Scott Trench says its pretty hot.

A ghost ad is where you take a great deal that has recently sold in your "hot areas" (the agent will tell you where those are) and you just post it as if it hasn't sold yet.

It will certainly make a difference, how much of a difference probably depends on how hot your market is.

This typically comes from a malfunctioning furnace or hot water heater.
