I am for sure biased but I would highly suggest using a real estate agent that is a) familiar with that community b) is well versed in selling to non-Mexican citizens and c) has stellar reviews.

From the 434,294 property records of my last (kinda old) snapshot, using a variety of property-centric heuristics I can generally find what I want to target, defining my TAM (Total Available Market) for my type of investing*.

Hello All,We recently bought a new primary residence using a HELOC and we now plan on selling our former one.

interst is charged on the loan through the date its paid off ....she could  contact present lender and  ask for a " payoff  statement "  using  a date in the future 

Not sure what state you're in but in CA I'd have to pay an extra $800 franchise tax for each LLC even if I set up the LLC in another state (I was going to do the LLC in Wyoming for anonymity using a registered agent). 

Is there a rough and dirty rule for sharing wells and using a common septic for multiple dwellings to ease up on costs and make things for efficient?

Having a Pre-approval letter or better yet a loan commitment and a Banker to call and reassure the sellers agent you can close in 30 days or less also offers a huge advantage.In this market using a DPA is not a bad idea since rates are high and when they drop you simply refinance for a lower rate and payment. 

Currently using as a STR.

@Jake Berlin- thanks ...I would recommend getting a loan approval  started  using a hypotehtical purchase price and loan amt ...This will allow you to get  organized/ educated and  prepared  and many of your questions will be  answered - good luck

If that's the case, you may be using a builder's agent as well which might explain why you don't know this stuff.The exclusive agreement should be for this property only.
