It is difficult for a condo to appreciate as an LTR and even more so as an STR when there are hundreds of other identical units and you have limited control over the property in order to force appreciation in terms of paint, renovations, adding a pool, adding pulll-up bars, adding a mini golf, etc. 

Ductless mini splits may be a good option for your application.

Our min is $75K loan amount.

Someone out there is dreaming of building a mini mansion (it's only 1/4 ac)

For instance, the overall scope of work can be broken down into categories that are done on a weekly bases and when payment has been received a waiver is signed for the mini-scope of work.

(**THIS IS ONLY FOR VERY EXPERIENCED BUYERS)  When you do your 2nd showing on a property you really like, schedule to have a contractor or retired inspector or builder come with you to identify any of the super major items that would cost a fortune to fix and do a mini inspection (IOW, test water pressures, run dishwashers, get outlet tester, turn thermostat up or down to check appliances are working if possible, etc.  

You might want to look into mini split systems.

I call it my own mini complex, but it wasn't super hard.

Ken Min I appreciate what I just learned from your post and would like to learn more!

You wouldn't have any recourse if she kept your new fridge and replaced it with a failing mini-fridge on the basis that the old one broke and the 'new' one was all she needed or could afford.
