It Has plenty of public road Front and power, but no public water or sewer available. property should sell for about 15k of the MLS, I offered 5k cash or $200 for a 3 year option to buy at 6k.

You said specifically that marking up a piece of real estate by 25% would put this poster into "predatory dealing waters." 

There are some good long threads about very specific details of MD and Baltimore auctions.In the spring I have people that help me inspect potential bids.

-About 500 sq ft of random areas of outdated 80s flooring-Water heater is from '91-A/c 6 years old-Roof looks good-Mandatory $100 social club fee at the Weston Lakes Country ClubThe house next door sold for 205k. 1740sq ft it sold outdated BUT had 3 bedrooms.

It looks like there won't be much need of repair -- I estimate $5000 at most.All the utilities are split out for the 3 units, except for water, which is $200/quarter.If I estimate 10% Vacancy, 10% repairs and maintenance, 5% capital expenditures, and 10% property management fees (I will mange it myself), I get NOI $11,362, cashflow -$212, CoC return of -3%I believe it's in a good location/neighborhood, one that I wouldn't mind living in, and it's close to Newark Airport.I would really appreciate your thoughts.

As for inspecting the plumbing, just depends on how old the house is, how long has it been sitting vacant, through the winter, what kind of water piping does it have, and what type of drain pipe does it have, just to name a few.

Expenses are low because tenants pay their own utilities except for water and trash.

generally the older the properties the higher the fees due to the cost of maintenance rising property taxes etc Fees also increase over the years but they should be matched to a well kept property as @Nick Britton said read over all the condo docs and especially the budget paying attention to reserves,expenses etc .I have lived in the Palm Springs area for a number of years and have see condi fees as high as $1000 per month on some of the older properties.If you a re looking at a investment in this area it has a host of problems as you noticed,rising fees is a big one.

I just signed up with Bigger Pockets and I am looking forward to this community and forum. 

Push the money into federal municipalities, state municipalities, and paying off your most profitable property in my opinion.Federal and state municipality funds are tax free investments, and mine perform in the 8-9% range, which means tax effective 11-12% range, equal to that of a decent cap return for real estate, plus they usually pay monthly.on top of that, the last thing the states and feds wont pay is their water, power, and sewage bills, hence why its a good steady flow of income.Also, it gives you three sources of solid residual income.
