What level of security or actions can be taken on my end?

Yes, the right way as not to be taxed more on your property value.And do you need a bank account dedicated to the LLC?

Every lenders rate stack is different, so unfortunately only your lender can tell you how many points it'll take to buy down the rate.Break even point = (difference in cost) / (difference in payment)If you think you'll refinance or sell the property before the break even point, financially it typically doesn't make sense to buy down in points (however, consider tax benefits if it's your primary as you may be able to write off the up front points -- which is considered pre paid interest).In you scenario (assuming a 30 year loan), the difference in cost is $3150 and the difference in payment is $52.

The $100,000 cost of the original structure in 2021 would not be depreciated further because it was demolished.So, for tax purposes, you would only depreciate the cost associated with the new construction, not the original structure that was demolished.

Location: Chesapeake, VA (large military town) Market Value: $360,000Loan Balance: $245,000Equity/Second position note: $115,000 (30 30-year amortization / 10-year Balloon Payment, 6.5% Interest, $727 monthly payment) - Bringing cash for this would save a ton of money for the buyer.Rate: 2.25%Years Left: 26Current Monthly payment: $1,300 (including taxes/insurance)Current Rent: $2,000Scenario 1: -If you were to purchase with a new VA loan at 7% interest at market value your monthly PITI would be approx.: $2,757-If you were to assume the loan and I carried the second note at the above terms your monthly PITI would be: $2,027Saving: $8,760 per year.Scenario 2:-If you were to bring the same $115,000 as a down payment on a conventional loan you would pay: $1,992-If you were to assume the loan and bring cash for equity position your monthly PITI would be: $1,300Saving: $8,304 (with no need to refi in the future)Since this is a hypothetical situation I'm going to give my number based on nat. average homeownership of 13.2 years.

These are reported and "retained" on IRS Form 8582.Of course, if you are unsure or would like additional guidance in determining what might fit your specific situation, please reach out to a CPA/Tax Professional who may be able to assist.

If you are interested in moving your entire portfolio, would you peel off (tax purposes) or dump everything?  

Of course there are discounts for security measures, gates, guards etc. that everyone would get but homeowners premiums are derived on so may factors such as insured age, household members, claims history, ROOF AGE, age of the home, scheduled property, pets etc., so if each home is individually owned this would be near impossible. 

If it's important to be near the Bay area then maybe consider the Tahoe Reno, NV market because it's only a few hours away if you need to go to the office and it offers a landlord friendly environment, low property taxes, and no state income tax.

Is your DSCR ratio greater than 1-meaning are you cash flowing (according to the lender's criteria of mortgage, property taxes and insurance (and HOA) if applicable).
