But I'm having a hard time estimating the cost of repairs like uneven floor joists, drywall install/removal of plaster, moisture in basement, electric, plumbing,  etc. 

Below are some generalizations about ongoing maintenance costs: Older properties require more maintenance than newer properties.Composition roofs require more maintenance than tile roofs.Properties in climates with hard freezes require more maintenance than properties in milder climates.Properties in locations with a lot of moisture require more maintenance than properties in dryer climates.Wood siding requires more maintenance than aluminum or stucco siding.Properties with lush vegetation require more maintenance than properties with little or no vegetation.Below is a typical Las Vegas single family class A home.In summary, I believe Las Vegas is not only a good place to invest today, it has a high probability of continuing to be a good investment location into the foreseeable future.

But this house is up on stilts and the dryvit doesn't have contact with the ground, but she says that moisture wicking is still an issue around doors and windows.  

You have to deal with the excessive moisture issue (poor ventilation, chronic leaking).Outlets not working in the kitchen is also not a big deal as long it's not a sign of major wiring problems (old wiring, rodent damage, fire damage, etc.).A single busted pipe is also not a big issue assuming it's the only busted pipe and not a sign of other possible leaks due to poor winterizing.

However the air was dry, so I found that reassuring.The mold and moisture in the basement was not included in the provided disclosure.My realtor just told me that a contract was accepted on the place, 2 hrs after we looked at it.My thoughts:  Its a good price, and even at asking the cashflow works and provides a $250+ monthly income.  

After the flood we were required to have a moisture test on the studs and certificate prior to closing back up the walls.

In addition to moisture/mold issues, I wanted to add also that if you have any laminate or vinyl plank flooring, the warranty can become useless and flooring damaged if the temperature is not kept at certain levels. 

It's also a great way to gently let your tenant know that you want them to take care of your property.

I've had luck with some thinner varieties but I've had thinner AC4 grade laminate buckle because of moisture.

I have no reason to believe there is any moisture issue from the building itself (and I've had more than one contractor come out, two even that put moisture readers on the walls and ceilings with no abnormal results).My question is, what steps should I take as a landlord?
