And, while I can't speak to Gulf Shores or the panhandle specifically, I know a number of friends that bought a property assuming Airbnb/STR would be the saving grace, to be out of the business within 18 months because they could never push rents because they had an ordinary product competing in a sea of ordinary product. 

you should get a RMLO or an underwriter to qualify the borrower. if its owner occupied and in florida you also will need to use a third party servicing company to service the loan which will run you around $450/yr. not an accountant but its my understnding unfortunately the interest income is going to be taxed at ordinary income and the principal will reduce the principal. how you offset the losses talk to your CPA.your best bet honestly is to just sell it and bite the bullet. 

If you sell property regularly as a primary business, or in the ordinary course of your business, you could be labeled as a dealer/developer and have your property classified as inventory rather than a capital asset.

Say you bought it for $200,000 and sold it for $250,000 and they put $50,000 down.Your basis is now $150,000 and the principal payments that come in from the borrower will continue to lower your basis and the interest payment is taxed at ordinary income rates.

Any damage to the wallpaper, paint, walls, floors, carpeting, doors, windows, window treatments, light fixtures, appliances, or other improvements to the Property (to include burst water pipes due to freezing caused by neglect or carelessness of the Tenant, his family, or any of his guests), in excess of ordinary wear and tear, shall be promptly repaired or replaced by tenant, at Tenant’s sole expense, so as to restore the Property to the same condition as existed prior to the commencement of the Term.

U want your parents to talk to their CPA FIRST.. if they go the development route they are now ( depending on the amount of units) creating inventory.. which will be taxed at ordinary income rates ( very HIGH)if they just sell they can 1031  and move on to something else.. many times when you run the math consider the risks of a partnership.. the sale of the land is far better than thinking your going to make some profit.. 

Definitely a less stressful way to do it the way you're describing, but I would say that 0 down time is a pretty ordinary procedure / SOP, unless a unit is getting significant renovations.

@Gavin JexSo you want a bank loan and then seller finance as wellA bank would not be in second position so they as the owner / lender would be in second.Also 0% they would still be responsible for taxes on that at AFR so if your payment is $300/mo the loan would go off federal rates so they would essentially have to claim around $5k in interest income which would be ordinary income so they may end up paying all of your payment in taxes… just fyi if they did speak with someone on thisSounds like a steal if deal for you
