Today they asked if they could caulk a gap under the kitchen sink.

Now it needs some upgrades, bathrooms, and the kitchen especially - but the layout is good. 

I am 26 working full time as a bartender and a part time real estate agent.

New roof, siding, paint, brand new carpets, kitchen appliances, bathroom finishes, and more.

So this might be strange and it might even be a good thing, I'm not sure, so I need some help deciphering the situation.In my duplex in Dallas I have tenants that has been with me for almost 2 years now, they have been awesome, pay on time for the most part and keep the place very very clean and tidy.However about 6 months ago they started to complain about little issues every time I saw them.Part of the weather stripping needs to be replace, the threshold needs to be repainted, need a timer to water the foundation.

The kitchen appliances could probably use updating as well.

It was her first time renting.

If it's a cash buyer it doesn't matter but you would sell it for less because the items aren't completed.So spending a couple of hundred dollars will help you sell your investment to a larger pool of buyers.Maybe adding A/C or redoing the the kitchen and bathroom might cost you 5 -15K but if you can sell the house for 30-45k more after repairs it's a great investment.
