Once you read the explanation below, you will understand how REALLY bad things can be if you don't get the letters but go through with the purchase.First, the owner/seller should have a clause in the lease requiring tenants to sign (or object to in writing) tenant estoppel letters if presented to them.

Primary markets will continue to hold their value though tough to make them cash flow.

This is the primary reason I prefer VRBO over Airbnb.

Then in a year move out and buy another home with the equity you have built up in the home.Great thing about buying a 2-4 unit as a Primary is you only need 3.5% to 5% down which ever on you choose either FHA or Fannie Mae.

VA loans, like FHA and USDA, can only be for primary residence purposes.

A Deflationary currency (which it certainly will be if population growth continues and no more coins are mined, and it is in fact the long-term "winner" in being widely adopted as the world's primary store of value) will not be tolerated by most. 

You can also HELOC your primary residence or RELOC the orange county property and transition that into cashflowing assets.

It depends on the lender but at a min they must follow TX SML or lending laws in the state in order to compliantly lend in TX, on whether choose to apply this guideline to all types of occupancies or transaction types (non owner investment, second homes/primary residences, etc)80-85LTV on rental properties is only on the purchase for fannie/freddie loans but on rate term refinances its max 80% and cash out max 75% for 1 unit and up to 70% for 2-4 unit cash out conventional.On HELOC's and rentals are up to 70-75% depending on the HELOC investor or product.Its good to distinguish between what the lenders are willing to do and for which product and also these loan products must abide my state law as well as an additiona layer of "overlays," on top as well (whichever is worst / most conservative).

These all require applicants to submit an acceptable Letter of Explanation addressing each specific issue and occurrence.Rental HistoryBecause a current landlord may say anything to get rid of a bad tenant out of desperation, we also require information for the previous landlord of all applicants.

As a general rule of thumb if the property has a ground level commercial requirement in order to show sufficient hardship to seek a residential use change the property should be located in a location that is not conducive to commercial use i.e residential street, close but not as marketable as properties located on neighborhood's primary commercial corridor etc.
