I did see a set of French doors, which I love, but I couldn't see the rest of the interior at all.

Here's the numbers:4bd, 2ba, 1200sqft private yard1700sqft, built 1991$48k PP$24k rehab, including basically all interior cosmetics + exterior + yard improvementsSeeing comps in the park around $150k for similarly aged homes.

As far as interior even the most minor changes is drastic such as removing all the wallpaper and replacing it with a fresh coat of paint. 

,wish it was that easy..but let me guess: your building was built pre 80's, the original builder insulated the exterior walls, and NONE in the interior/between the units/up/down/sides....

@Richard Stephens The reasons why Comps fluctuate are due to differing layouts in terms of the number of bedrooms and bathrooms, total square footage of living space, quality of interior (updated kitchens with stone countertops, stainless steel appliances, updated bathrooms, type of garage if any, etc.) that varies from market to market.

The place was in terrible shape but I managed to complete a full interior remodel while living there with some help from friends, youtube videos and some paid help.

The interior photos were... eye opening.  

Walking the property (interior & exterior) provides a great opportunity to discuss any maintenance items with the tenant and give a gauge of how current condition vs move in condition or past inspection condition.

The only thing we requested outside of the contract was all new interior doors which we provided consideration for with the painting money being signed over to him.
