From their point of view, you are ruining someone's vacation, and can't be trusted to supply a good product (your property). 

If anyone has any recommendations for me on what products I should look at and where I should buy for bulk prices let me know. 

What are you hoping to accomplish with either product?

Depending on the lender and the product if it is non-comforming you may not need to wait that time and you may not receive a LE or CD, but still most lenders will have it as a standard practice to be safe.

Right now I am dealing with a DSCR lender that switched my client's product to a Bridge loan and gave him a very hard time when he asked for a copy of the appraisal.

It sounds like you already have a great foundation with your rental and BRRR experience in the UK, and you'll find many similarities in the US market but also a few key differences.For location, I’d suggest looking into markets with strong population growth, economic stability, and landlord-friendly regulations.

If all adults are screened, you can avoid potential legal issues down the road, especially in cases where one occupant engages in illegal activities or violates lease terms.Financial Stability: Screening all adult occupants also allows you to assess the household's overall financial situation.

Chances are they are not coming off the price, because your home inspector didn't agree or like it.That's the standard with production builders. 

Assuming he actually got the majority of his capital back in each of his 10 or so BRRRRs (which seems to be the case) he's likely accumulated a good amount of equity and is benefiting from debt paydown and tax advantages (with potential appreciation and improved future cash flow once the properties are stabilized being nice-to-haves if they happen).

Your deed of trust needs to be made by the trustee, or you didn't properly perfect the security interest, I'd bet on any attorney getting that right unless they were really new.Back to the other issue, any lender advertising a loan product and never closes that product can get nailed.
