@Natalie JohnstoneAll real estate you're making some assumptions. 

Here we have an example of unspoken assumptions and changes in classifications and/or treatment of classifications.

I believe your assumptions are correct, only there is no requirement to buy again for the primary 121 exclusion portion.

I was under the assumption that the road leading to cabin was a public road as it is named and marked on all maps, apparently not.

@Tim PhillipsRecommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.So, when investing in areas they don’t really know, investors should research the different property Class submarkets.

My assumptions based off research is I will be able to deduct 1/2 of all allowable expenses based off the ADU square footage (My understanding of that list below)  1/2 Mortgage Interest (Not principle) 1/2 Utilities 1/2 Property Taxes 1/2 Insurance (assuming I don't have separate ADU insurance)  1/2 general house maintenance (depending on the issue and if it's related to the ADU)  1/2 Depreciation (Home value, not land divided by 27.5)  KEY QUESTION: If my mortgage (PITI) is $5400, and all of those ADU deductions equal $3800 monthly, and my ADU income is $1800 monthly, am I allowed to pay the difference in "deductions" from my real estate business income?

You need to be an expert in the market to make sure you can hit your assumptions and you can achieve the income and expense projections.Hope that helpsGino

“Because the $20,000 took so much away from their equity to put into another home, they decided not to sell,” she said.Another client of Chaname had difficulty selling his home because would-be buyers balked at paying $16,000 more for a home with HERO-financed air conditioning, duct work, water heater and insulation when similar homes were selling for less.The buyers argued they were paying for the improvements twice – through the higher valuation on the house and assumption of the loan.

I don’t know how to analyze my numbers to make a decision and I’m not sure my assumptions are accurate. .
