We currently have our auto (in California) and our 2 Texas rentals with Liberty Mutual.

I am selling property through seller financing and the buyer would like to have the payments auto deducted from her checking account.

On the car wash business... this deal is to purchase 2 separate car washes in one deal, they are 2 auto touch free washes with 4 manual wash bays.  

I'm a local business owner here and always have been interested in commercial real estate (shopping/strip center or individual shops) I'm in the automotive industry so my ultimate goal would be to buy and rent warehouses/auto shops. 

I would like to draw on my background which includes a bachelor's degree in Mechanical Engineering, control system design, sales and proposal writing.

Yes... take monthly MI especially if you know that your ARV or "after repair value," is at the very minimum 125% of your loan amount because this in essence means you have 20% equity (IE 100k ARV / 80k loan amount = 125%) and you can get your MI removed automatically after 12 months min (some mtg servicers vary but most are min 12 months for auto removal w/ equity documentation). 

The LLC is simply the reporting mechanism to record the property's sale and to determine how much of the the resultant tax gain from the property's sale gets reported to each LLC partner/member on the Schedule K-1 issued them by the LLC.The partnership should receive the sales proceeds (it presumably made the sale - correct?) 

There are some additional discounts for having auto insurance with the same company but I didn't include those.What does the HOA cover?

Builders warranty is also something that looks great for an investor. 1 year covers materials and workmanship2 year coverage on all mechanical/ electrical and plumbing 5 year leak protection internal or exterior infiltration 10 year structural Love to hear thoughts on buying new construction?

How you ultimately financed it, upfront when you purchased it (or how you might refinance it later) is irrelevant.Just do a simple search on the internet for depreciating rental real estate property, you will find a virtually limitless number of sources that can explain basic depreciation mechanics - its not rocket science.
