There are fewer people reaching into your pocket.I'll suggest what I've said to another ambitious first time investor out here in LA, do a small deal or two (say a duplex or 6 unit apartment).

I may have a spreadsheet for what you are trying to do with these comps, but it is late and I am ready to hit it.Recommendation: If you can outsource finding your comparables and/or doing databases and spreadsheets, because they are time consuming and your time will be better spent on speaking with Seller's and getting the properties under contract.

I think Fort Hood is supposed to lose a total of fewer than 4000 Soldiers from a local population of approximately 200,000. 

I don't actually know if many investors would have a need for this type of automation, but I would happily write code that could help systematize some of the time consuming parts of someone's day in exchange for any knowledge or experience they'd be willing to provide.

Lower tenant turnoverLower capital costsLower operating expense loads relative to other RE asset classesAccelerated DepreciationStrong demand via continue economic pressure on the middle / lower class + boomer retirement with insufficient savings Higher cap rates relative to multifamily assets of comparable qualityA few differences of 55+ vs family parks:Smaller customer base (perhaps not true in Florida)Higher operating costs due to increased amenities (clubhouse, pool, shuffleboard, gym, RV Storage, etc.).More organized tenant base with more time - might push for rent control Far fewer bad tenant problems - likely fewer collection / eviction issues Likely easier to finance as there are typically fewer park owned homes and the communities are more visually appealingLower going cap rates so one could argue higher risk, but lower exit cap rates so if you can dramtically improve the parks operations, you'll make a higher multiple for every marginal dollar of improved NOI.
