It looks like this lady works for a local homeless shelter, which makes sense how she knew to file the complaint with this specific non-profit the day after it happened.

I've kicked around installing AC but still manage to get renters applying to live there before I pull the trigger on installing AC. 3 - 2nd Duplex - I installed central air after purchasing the property for inherited tenants but they've used their own W&D units for years.

We will examine after the first initial cleaning to see if they go above and beyond or do the absolute bare minimum. 

Maintain the absolute highest standards of appearance, cleanliness and service and families will be beating your door down.  

Is it (a) pre-offer (b) after an accepted offer but before contract signing (c) after contract signing during a due diligence period? 

I have been in touch with the folks at Real Estate Sales LLC and FlipCheapHouses.com.

Make 20% increased payments for 2-3 years, stockpile your cash and after 2-3 years pay it down more if you really like. 

I only tried the higher quality because of a sale and didn't see the value.

Could maybe get an extra 15k after the full rehab.

After that, go for it!
