The land is currently zoned for light industrial use and is occupied by several auto repair shops.

I don't know quite as much as Detroit but I am pretty sure that prices there are still lower than they were in 2008 before the auto industry there collapsed. 

To the extent that a price reduction may make a "stale" listing appealing, worry not, you will get those notification emails on auto pilot anyways.Start doing the compare and contrast, maybe make a spreadsheet to evaluate opportunities, play a game of "spot the patterns." 

If you have it fully renovated, including mechanicals, roof, etc.

In most states it is very easy to file a mechanics lien against a property owner. 

I'm looking to build a 2500 sq ft two level ecofriendly single-family home which incorporates natural surrounding into the design, I'm trying to figure out what my cost should be for architectural plans: elevation, floor plan, mechanical, plumbing, electrical, etc.  

These would be properties with good roofs, windows, siding, and mechanicals.2.

I'm pretty convinced Latchel is just an auto-reponse generator with outsourced support.

I've seen quite a few people use Auto Owners for STR policies recently.

Are you making any monthly payments on the auto loan?
