I ask for  mortgage release if there was an old mortgage.I then get title insurance and can sell with a General Warranty deed. 

To the best of my knowledge, I do not believe that I am qualify for Solo401K but will validate my understanding with my CPA in my upcoming session.3- Yes, you are correct.

Recently I have found almost all the cases where the owner name in county record is different from what applicant stated. this made me wonder if my assumption that name should match in county records is valid?

There are many other benefits to this strategy.PM does take some of the load off on the front end with new construction, but the new home builder warranties are good in Texas & their warranty services are online.Good for you buying new!

Its a standard form that you never see as a consumer but lenders use it to validate things on a mortgage - like if you have paid on time and if your mortgage is in good standing. 

Your concerns about liability protection are valid, especially as your portfolio grows and the legal landscape evolves.

think about your first 1 to 2 to 5 to 10 years of ownership of a property, and the difference between:-a 1-year old furnace under warranty, and a 35 year old furnace-a house with central air, and a house without-a house with a brand new roof, and a house with a 25 year old roof-a house with a knob and tube wiring, and a fully rewired housewhich is going to have more capex? 

Make sure it is a valid reason that warrants a refund etc. 

It’s a valid concern, and one that I've faced many times.

A fire etc resulting valid claims in excess of your insurance coverage can wipe you out otherwise.
