A few examples that you can explore directly....1) Is there biological resource value i.e. wetlands or other 'special' habitat?

@Greg TunesThere are better qualified people on this site but what I would do:Speak to an attorney whom specializes in quiet title.Are the taxes up to date?

If you specialize in low income housing then it is fine, but if you prefer more workforce housing I would not buy in Fairmont

Please be advised, I'm currently in search for an Attorney that specialize in SUBJECT TO mortgage contracts and closings, located in MARYLAND.

." - solve that without involving a C-corp.And if I'm not mistaken, if you buy in a land trust with an LLC as designated beneficiary, you can change that without changing title.You need specialized advice, both from lawyers and CPAs.

Others specialize in preforeclosures, probate, tax defaults, non-owner-occupied, etc.

They will look out for you and you will do the same for them.Your first purchase is going to be special both emotionally and financially and you will learn a lot from it.Good Luck and Thank you for your service (hope I got that right)

They respect the property because they are your friend, or they routinely expect special treatment from you because they are your friend.  

I notice in IRS Publication 537 that real estate dealers are forbidden from using the installment method and must realize all the gain in the year of the installment sale however it references some special rules in 26 U.S.

That was a special program back then, not sure if it's still done.
