No situs address, owner or owner's address. 

Economic aspects are scarcity, modification or improvements, permanence of investment or fixity and area preference or "situs" which may include intrinsic values or satisfies other needs.Real estate is unique, drop back to your Economics 101 class, "factors of production" in economics are land, labor, capital and entrepreneurship. land is the only factor that can not be replaced as a factor or requirement to produce goods or services, all other factors may be substituted, if you have less capital, more labor may be used to obtain the desired outcome. 

You could make your own OO list - get the data from the county and compare the situs address vs the owner/taxpayer address field.The brokers charge a lot for data, so much so that it's really not an option for beginning investors. 

If you want a fixed 15-30yr low interest conventional loan most lenders will require a foundation and as @Jeffrey H.has stated it must not have been moved from its original situs unless it is coming directly from the factory or a dealers lot. 

so the people losing them are bombarded with letters much more so than normal non situs type letters.

But my understanding as a layman is that Nevada has charging order as sole legal remedy, so if you are attacked personally, and if there is no veil piercing or fraudulent action on your part, the asset of your Nevada LLC should be protected from you.However, if your property is in Florida, you will not be able to act in court as your Nevada LLC has no situs in Florida.

developing land the right way will take a tremendous amount of mental power if you're deciding to developing the land for an investment venture to gain a Rate Of Return (ROR)  on your investment and structure your deal to accommodate a healthy percentage in leverage to minimize risk.. you'll need to really really focus and forming a business plan before anybody touches a hammer.. we need to analyze a lot of different variables before we can accurately determine if the investment is worth the time.. focus on the type of property you would like to build first.. if your devolping for an investment you need to research your areas demographic real estate "situs" the situs is the hottest location in your area for buying and selling of homes and in each hot location theres always a certain style property that sells the most weather its a 2 bedroom 1 bath or a 3 bedroom 2 bath regardless you need to analize your areas demographic and once your determined the property type you need to get an engineer to draw up foot prints so you can present the floor plans to a contrusction compnay and rememebr this is an investment to so any way we can minize our expiences will ultimatly grow our profit so you need to get bids from several companys and you need to ask them their estimated time of completion becase that can affect profit to... when you have our cost to build the home you need to perform a residul land method approach for determining the maximum purchase price of the last.. we can determine this by minusing the market value of the home from the cost of construction devided by the percentage you want to see if profit from just the last and home alone but when we determine the value of the home we will use the Net Operating Income Approach so we can determine the capilization rate if your planning on renting out the propeorty for a monthy net profit for first you need to determine the average time it takes to get a tenant (usually one month) so be aware youll have to pay all the projected expenses for a month so for the valuation we need to take all the property expense like homeowners insurance, property mangament fees, utilites, property taxes cost cost, ect (not including cost of construction) the based off your market you need to determine the prices to rent that home monethly then minus the gross income accumlated from monthy rent and minus that value with the projected cost to find your Net profit. one the net profit has been calculated you need to determine the averge capitlization rate for your areas income generating properties but keep in mind this cap is just for the purpose of determing property value.. ultimatly your levering way more on your investment due to lowercost in obtaing the asset but youve called a broker and recieved your areas average capitalization rate or your personal desire  capitlization rate you simply devide the net profit for the year and devide that value by the cost of construction that will give you a percantage of the profits your going to be yeilding per months in net profit just on the building alone then we need to determine the actual value of the home will be considering the average cap rate 7% for example you would multiple the net income for the year and multiply that value to the 7% to get the value of the home. one you have the value of the home you minus the cost of contruction to calculate the MMP of the land it self.. for example with a cap rate of 7% the building would then be valued at 500,000.00 then we need to minus the estimated cost of construction 200,000.00 wich leaves us with 300,000.00 but if you are planning on selling the propeorty right off the bat you need to apprais the home through a CMA approah to get buyers point of view price and not an investors point of view but if your do sell the house after construction you need to deduct the desired percentace of profit you would like to yeild of your investment so for example we determined the home value is 500,000.00 and the land ls valued 300,000.00 totalling 800,000.00 - 300,000.00 for the land aquisition - 200,000.00 for construction cost will net you a margin of 300,000.00 or keep the propeorty and rent it out for a very large cap rate and make yeild on and extrely high leveraged deal and build wealth through appreciating and equity then possible sell the home after youve built up the operations and minimized expense and maximized your profit resulting an inflation of value based of NOI then you have create appreciate through propeorty operation or maybe through market growth.. if can also determine YoY market growth allowing you to calculate future rental rates and the calculating a new NOI resulting in the new property value.. determing growth in the value is a good step to take when holding onto an investment property.. 

It is also reimbursing my vehicle mileage and medical expenses.Also you may need to have the entity registered in the state where the properties are as you need to have a local situs if you need to start an eviction or other legal action.

Maybe even send it to the situs (I'm assuming mail will be forwarded to the Ex?)

Buyer immediately files Memo of Agreement in the situs county.
