The adjacent property to mine is a small acreage vacant wooded tract that is abandoned.  

It is taking me time to digest everything.

You need time, as a first-time buyer, to digest this.

Kevin,I wouldn't consider it a deal breaker, if you feel the price is good for the property. so you or your landscaper have a little extra work cleaning up, that shouldn't make or break a deal. as far as your concern of the tree. you never know when any tree or branch may come down, if trees are your concern then why not look at property on tract land where they clear cut the area?

There you will be able to see the "raw data" rather than a "digested" form.

Much more material to digest than time in the day!

I would like to digest it to see the counter arguments for massive govt built and subsidized housing.  

You might also look at conventional options too, as there could be 5% down options via Freddie Mac, depending on the area/census tract. 

It has income limits by census tract, but here in the Bay Area surprisingly large swaths of real estate (eg, 90% of Oakland) are "no income limit" census tracts because they are looking at 2010 Census data (eg, middle of the Great Recession when the mortgage industry was imploded) to determine which census tracts are "under-served" by the mortgage industry.

However, I think @Elizabeth Wilson and @Jonna Weber are on the right tract suggesting house hacking.
