When purchased was with a package deal so I made the mistake of not just taking care of this at closing but, here is the deal. Three separate lots with one empty, one with two story quad and the other with 2 houses. I had not seen this before but the legal description is the physical addresses of the three structures and not Block x lots 123 as normal here in Golden Triangle, South east Texas. I just want to separate quadplex and lot together as one deed and property (lot has easement from power lines so gonna put 4  car garage, parking and covered parking to add income of rented garages and spaces) then separate two houses that are on the same lot as separate deed and properties. Keeping clear of commercial property by having them all remain sfr 1 to 4 unit parcels. one house will be converted to duplex and the other just sfr rental. All of this is no big deal, Talk to city, they just want to see survey plotting the new arraignment, they get their $450 a lot ($1,350 all in) and city/county is good. Problem is I called three surveyors recommended from our title company and two others. Only got one to give a quote and its $3,400 plus tax plus city fees, This will be $5,000 easy when all done. Sounds really expensive to me. Usually pay 350 to 750 for survey. and the 750 was for a commercial deal. 

Anyhow, hope I explained well and just wondering is that # high in yalls experience?? and if it is, does anyone have a good surveyor in Port Arthur / Beaumont area of Texas???

Oh, And they said it would be 4 weeks. This really is a simple thing. three identical lots, two combined, one separated and split even....... 

If 3400 is on spot then I got to get a second business going here...lol
