I understand that banks will usually refi up to 75% or 80% LTV, but I have a question about the seasoning period.

It sounds like you need to talk to several mortgage providers to get their input on how the property will be valued, ] seasoning requirements, whether they will count the rental income, and your general qualification for obtaining a loan.  

We've already purchased a home in Dallas as new primary residence.We have opposite opinions, so any advice from seasoned investors is appreciated!

I plan on doing annual leases, so it would not be a seasonal thing.   

Many lend based on loan-to-cost instead of LTV or ARV and at least a year or two of seasoning is required.  

I initially didn't consider the winter season coz the property is so close to the base that most likely my tenants (future) would be military and we don't go any where during the winter season anyway.

That's flip flopped a bit and I now find myself working full time at accounting and taxes (particularly since it is tax season now) but still squeezing in time for real estate (I've bought two condos since tax season started this year, one of which is needing a full gut job.  

I love running the numbers on potential properties for practice and am willing to help out more seasoned investors in any way that I can.In summary, I truly look forward to interacting with the community and contributing in any way that I can.  

So I'd remove the tap or put a lock on the tap that's outside your garage, or lock the electric panel and shut off the pump so they can't access it for use.Water is expensive and you can call city to find out cost so if you decide to let the HOA use the well I'd get your HOA fees credited or have the HOA pay you direct..Your electric for running the pump is an expense, and I bet they've used it season long to refill pool when needed. 

I plan on talking to some local banks and lenders to see how viable a refinance will be after the rental property seasoning period with my families current financial situation.Check and Re-check the numbers on the deal analysis.
