The $1M raise is barely enough to make the attorney fee worthwhile. 

I know that between Google Earth Pro and county-maintained GIS platforms it is possible to get a lot of property information for free, but I imagine that for folks without day-to-day experience, it can be time-consuming and often frustrating.On top of that, often times data is unavailable in less urban areas or available only in paper or PDF format which means scanning photo-copied images that are barely readable.

You don't know that John's tenant is barely surviving financially.

In order to make money I would have had to do the bare minimum to the units and just ignore a lot of the problems.

I have the money to pay off the the seller's second mortgage right now, but barely and I'll be robbing money that's going into my current project.

Now Bare with me as this is my first post and ill keep it short and sweet.

I've never dealt with Septic in a park, but plenty of experience on SFHs.My advise would be 1) Find out the age of the tanks 2) Find out the material they are made of (concrete or plastic) 3) Same for leach fields.Reasons being: Old concrete tanks are far more vulnerable and likely to fail soon....the newer plastic tanks will most likely cause you no problems for a long time.So if I personally were to find out that these tanks were all plastic, and <10 yrs old, I would barely even worry about this.

You will make no money along the way and your renters will barely be paying your rents.

Have them put the construction loan on the bare ground.  

@Sean MIddleton My bare minimum is $230 per month for vacancy, repairs and capex.
