It seems like a huge number of BiggerPockets users are looking to quit their jobs and transition into full-time investing.

The rents are below market, the current owner does not charge any rent for outside parking spaces, the parking garage rents are below market rate, there is a beautiful unit being used as an office that could command $900/month, storage fees are not implemented, water is being paid by owner, etc.

I say this to help you get a larger return in the future and help command larger rent sums.

I believe they have a subscription system however from what I recall it's a little bit expensive and is not very user friendly.You can pull the public data from the various websites and then go and extrapolate everything, but unless you've got a pretty good programmer who can build out some engines to go scrape everything you will end up doing a lot of that mining manually.

The exposure is negative cash flow.The last Great Recession is owner had to use rent to pay for his own mortgage since he lived on high leverage and lost his job.

The system is user friendly on both ends.

Is it worth it to spend time retiling this bathroom my self or is it fine and won't command much more in rent?

Units are in good condition, but could use some updating which could in turn command higher rent rates.  

Not sure where your building but I wouldn't accept anything less than 1.25% monthly rent/value..With the cost to build where it is, it appears that building single family for end users is the way to go..

If the market is at $1000 per month and your property is comparable with houses commanding that rent, then you should raise rent immediately.
