Other states have higher rates, or maybe they buy Florida certificates at a discount from other investors.

Only low end and deeply discounted are moving here in Houston

That is each, although I would expect a discount from a contractor that did both at once.

Discount on labor for doing everything in one install (savings of $400)Cons: More expensive up front cost.Removing kitchen/dining floor before the end of its useful life.I prefer uniform floors in an open space, so I'm leaning towards Option 2, but I don't know if that's a wise business move. 

With your SFR experience, you would know how to pick good opportunities and operators.Selling or exchanging 20 SFRs for a single property is impractical...would likely have to involve a portion of the portfolio (or a discount to a single buyer).Many investors would consider having a 3rd party PM handling 20 SFRs to be a limited amount of work on your part.

I am looking at starting google ads with my website where I plan to get people to sell me their property at an extreme discount.

One interesting thing about where I live is that I can buy them across the state-line at 0% sales tax, but that means I have to install them myself.I wonder if Home Depot or somewhere similar would offer me a discount if I buy 1 Fridge, 2 WD all at the same time?

I have close to 200 doors now and I don't get any special discounts from vendors so let me know if you find some that do...The market for good contractors seems tighter than the market for good rentals here now :) I will say that the guys I have used for years that are really good always treat me fairly, move me up on their priority list and sometimes throw in extra work to help me out. 

We do not offer a discount since it is required.

With AMFAM the inital rates are $200 less than state farm - but they have a welcome discount now and I guess I would lose it next year and the rates would go high.
