I have over 40% equity based on loan amount of $200K and general market value of the property at $400K (unsure what assessed value would be).I'm thinking I'm a candidate for PMI removal.

If you do, you are missing out on most of the advantages, and rationalizing bad deals into good ones based on "%'s" instead of dollars. 

The tax treatment of your land sales would typically be determined based on when each parcel was sold and whether they were held for investment or business purposes.

Yet, you can do online searches and, most importantly, use your common sense.A few days ago, one of you asked me what I thought about a particular development in Tulum he was thinking of buying into.

Appraisals are based on comps so probably negligible value diff.  

The truth is, it’s based on a multitude of factors and ultimately comes down to what makes sense to you.

@Josh Mac are they wifi or cell phone based? 

Do a search and you will find a ton of info on that topic.Personally this is not something I would do.

And again, this is my market and area of town, but tenants like the character of the older home with the tall base boards, hardwood floors, arched doorways between rooms, etc.  

In the meantime, offer based on what the tenants are paying now.
