Best Value adds are:Updated kitchen, updated bathrooms, cosmetic remodels.Additional bathrooms - finished basement spaces, in unit washer dryer, central air, additions/alterations.All of those are useless though if your roof is 30 years old, your mechanicals are from pre 1950's, and your home is in dire need to be renovated "behind the walls"Otherwise the above will increase your value but you will be left with Lipstick on a Pig

Maintenance/cap ex, insurance, if a rental PM, bookkeeping, misc.The fact you have a loan means 1) leverage 2) equity pay down.In addition, there are tax benefits.So I will do some rough underwriting as an OO non-rental at 95% LTV (because FHA has some undesired consequences that make the 1.5% difference in LTV worth avoiding the FHA).equity paydown: 20% (using OP interest rate at 95% LTV and not counting closing costs). 

That said, if you feel you want to go above and beyond, then could could try contacting some of these apartment complexes directly and confirm her story with them but if you can easily find another qualified applicant why would you take on this work and additional risk.
