Signed the papers, mailed in my money, and I was now the proud owner-to-be. . .but there were unexpected obstacles.The foreclosed owner remained in the property.

Most everything has been performing as expected with very little unexpected occurrences. 

You can run your own comps on Zillow/redin  make sure you understand your local market and how much finishes, bed bath count effect prices, don’t lie to yourself about arv or project it to go up that’s how you end up in trouble.if you can get all those variables down, while things can still happen/go wrong you should have a good ball park of the potential profit margin, always room for error in your net profit, markets can shift, you can get hit with unexpected expenses etc. 

Vice versa, if you are just starting out, you might want to be more conservative to tackle any unexpected expenses that arise.The 70% rule is an industry standard, but that doesn't mean you can't adjust it based on your desired ROI.

By the time it reaches the tax sale, the property has often been vacant for many years, with all the electrical, plumbing, and HVAC components having been stolen. 

The original ownership was very smart in that it has a campground component and there are over 300 houses in 318 acres.

Therefore, it's vital to calculate these costs before purchasing the property.Seeking the help of a 🏗️construction professional is recommended to create a comprehensive budget that includes hard costs (materials, labor), soft costs (architectural and engineering fees), and contingencies for unexpected expenses.

. $8,800 to 11,000.00 is more realistic because like most guru's they hold back key components unless you pay more for them. 

Now, I've been a buy and hold investor of mobile homes but have also added a wholesaling component to my business.

He told me since I just bought this building; I can depreciate the components or something.
