It is very outdated and needs a lot of work but the bones of the house are good. 

This is the property info:Located East side of Hollywood, FLFourplex consisting of (2) Studios and (2) One BedroomsProperty is in good shape but outdated, needs: (4) new bathrooms, fresh paint, maybe windows Current rents are $4,150 totalMarket rents are $5,600 total (Conservative) I would be inheriting tenants, so I would have to go through the process of vacating the units, renovating, renting. 

Yes, that post has limited information, is outdated & would be irrelevant in this case. 

This property is a B- or C+ rental (clean, but outdated).

Unless you're going to invest in a higher end door, they tend to look outdated.

Get a realistic move out date from her and find out what has to happen to make it a reality - or find a way for her to stay.

The kitchen is very outdated and so is the bathroom.  

Anything that charges 3 cents to 8 cents will give you outdated data and a lot of wrong numbers.I use IDI data and help others skip trace their data because the contracts are costly if you're doing less than 5 deals a month.

@Marco Pangilinan In the list of pros and cons of working with section 8 there is a "con" that is "the inability to control the move out date" and it is because your tenant moving out is not able to control the move in date on the other side.  

Pros: Likely result in renting the property faster, higher rent of about 4 - 6% and if I sell in 15 years, the look should not be too outdated (I hope).Cons: I lose a months rent, upfront cost that I lost to invest now, my time and effort, long return and risk of the project going over budget or take longer than planned.Should I just clean it up and rent it ASAP or invest my time and money?
