FHA home appraisals must note defects such as broken windows, unsafe electrical systems and inoperative heating systems.

(I’m not even going to add on the extra two or three months of lost time, expense and rent, if the tenant files for Bankruptcy.)So, with regard to “professional tenants,” your statement that “they will not drag it out for months is Texas,” is false.You also stated that it was “fine with me” if the tenant files an appeal bond.Well, it won’t be fine with you when you find out that the sureties on the appeal bond do not possess sufficient resources to pay the judgment and costs.This is one way professional tenants "game" the system.They file a worthless appeal bond and not a pauper’s affidavit.This way, their action does not trigger the requirement of paying rent into the justice court registry.However, the bonds they post are defective or supported by sureties who do not possess sufficient resources to pay the judgment and costs – a fact the landlords often find out too late.Biggerpockets used to be a fun and informative place with a collegial atmosphere.However, I’ve noticed that a lot of know-it-alls, self-promotors, and unsavory characters have weaseled their way into the forums and podcasts for nefarious purposes.

It had too many defects the dealer said was "normal,"  like the window regulators breaking every 6 months.

This situation is largely due to a set of laws that I heavily criticize regarding builder defect laws.  

But now that I am looking over the lease documents and there is this section already in there: "All personal property placed in the leased premises, or in any other part of the building, or any place appurtenant thereto, or inany vehicle on or about the premises or on any parking facility maintained by Lessor for Lessee shall be at the sole risk of Lesseeor the parties owning same, and Lessor shall in no event be liable for the loss of property of any kind, which may be lost orstolen, damaged or destroyed by fire, water, steam, defective refrigeration, or otherwise, while on the leased premises or in anystorage spaces in the building.

Unless there was something in very fine print which stated a major plumbing defect, which I missed.

Within this, he will let me know of any structural defects (red flags), electrical, plumbing, roof, etc issues.

What guarantees or assurances can you provide the private lender that with each purchase, there are no additional hidden, unrecorded or other liens and title defects that could be discovered subsequently and that could materially erode any initial estimated equity or profit?

They are selling you defects for premiums.  

No having read every post, forgive me if I'm repeating but I'm pretty sure liability works something like this: If you KNEW about a defect which then causes damage, you are liable, but ONLY if you didn't make efforts to rectify it in a suitable amount of time.
