A solid pre-screening of the contractor upfront that spells out the expectations should somewhat reduce or eliminate the question of one side bailing out on the other.

@Bao Vu The purchase price and related expenses from 2023 should be included in the cost basis for the flip sold in 2024, reducing your taxable gain.

This reduces exit options and affects the value. 10) Small number of small units is the most expensive residential development there is.

However, for a commercial property or a commercial residential (5+ unit) property value is based on the income approach and reducing expenses in this case by producing electricity factors into that math and very well might increase the valuation enough to make sense.

If you work a day job in addition to your plans to pursue real estate in this way, then focusing in 1 city/MSA will drastically reduce your time spent focused outside your job, allowing you to keep your income high, your job safe, and your problems simpler.

@Saika Maeda Permitting the ADU allows you to claim depreciation, operating expenses, and other tax deductions, potentially reducing your taxable rental income.

I keep thinking about tools that can help me reduce risk by catching errors or red flags in seller disclosures and inspection docs, but that's likely because I've had a bad experiences with both.A simple and obvious example is a seller checking "No" for pests section, such as Scorpions and Snakes in Arizona when the property is in the desert, so obviously, there will be snakes and scorpions. 

An option for you could be to go with a DSCR loan with a reduced prepayment penalty period so that you can get funds soon and if you want to refinance next year or the following due to lower rates or wanting more LTV than you're able to do so.You should look at this one with the mindset of:1) What would my expenses be once I refi vs what they are now?
