I have others that can close in just a few days, if that's your priority.I'm happy to share my experience both as an investor and as a lender.

Looking for various tax strategies to reduce the reality that a large RV or boat is a grossly depreciating assetI would not have a loan, so claiming it as a primary or secondary residence and claiming the mortgage deduction is not applicable.I sold my primary residence and I have several rental properties which I use as I'm fixing them up.What I'm pondering is living aboard and working aboard developing a new product, while traveling.  

Commercial deals are going to look at your qualifications as an investor as well as the DSCR value of the property supporting itself (at least here in the USA).For construction, you will need to look into licensing requirements such as a GC license.

Yes - and even when its out there its typically impossible to qualify (need high rate and high DSCR and typically would have to qualify as a LTR - so almost a unicorn or in a really bad market)

Even as a Foregin National you can still take out up to 75% Cash out depending on your citizenship. 

This is most of the depreciation you are taking year one.You can calculate your depreciation recapture by taking the sale price of the asset and subtracting the adjusted cost basis.The adjusted cost basis is what you paid for the asset plus any improvements you made along the way minus the depreciation you took along the way.The profit above this original cost is taxed as a capital gain, but the part linked to depreciation is taxed at a maximum rate of 25% under the unrecaptured gains of section 1250.To recap the tax rates are:- Sec. 1250 real property: 25%- Sec. 1245 property and 15 year 1250 property: Ordinary Tax RatesThere are ways to minimize depreciation recapture especially if you know how to work smart with your CPA.1) Asset Valuation at Time of Sale - Sellers can minimize recapture by reallocating the price of the assets on sale.

Not sure how long you held the land, but there are some instances that the land can be used as a down payment. 

Here’s our OPINION for the Metro Detroit market (use as a template for your target area!)

Accountability must be demanded by Californians, and the nation as a whole. 

Now if your thinking location jumps out as a big factor to all this, you hit the nail on the head, location location LOCATION.
