Most of my clients that are doctors, typically will want to purchase real estate to not just yield the benefits of RE, but also for opening their own practice.

Hi BP Community,  I have a short-term rental (previously Airbnb) that I turned into a long-term furnished rental because the neighbors house was damaged by a storm.

Especially with a long-term hold approach.

The intent is the sponsor needs to know enough about investor to feel comfortable the investor has the financial knowledge and acumen to properly evaluate the potential risks and benefits of any investment and the financial stability to invest capital for a 5 to 7 year period.Topics of discussion with sponsor would be:Income, credit, job stability, prior investment experience either with real estate or other asset types, education level, occupation and profession, amount of savings or funds in retirement accounts.Hope this helps.

You're implying that you want to squeeze some tax benefits by structuring it as some kind of renting from yourself.

It's Alot I want to dive into that will benefit me income-wise short term long term.Looking forward to connecting with you all.

Cap Rate is a term only relevant to commercial properties.  

We've done this many times where you purchase a property at a discount with short-term financing/bridge loan, rehab it to increase the value, rent it out and then when you refinance it with long term financing, you (hopefully) get some money back.

.- Investment Term: 5 years - 10 years- Equity Split: Investor 80% / Sponsor 20%.- Preferred Return: 8% annually to the investor.- Profit Sharing: After the preferred return, profits are split 70% to the investor and 30% to the sponsor.- Management Fees: 2% of gross rental income annually.- Acquisition Fee: 2% of the purchase price.- Disposition Fee: 1% of the sale price.Option 2: Debt Financing with Equity Upside- Target Properties: Single-family homes, multifamily properties, and land for development in prime locations.- Interest Rate: 6% interest only for a term of 5 to 10 years- Prepayment Penalty: 2% if the loan is paid within the first 3 years- Equity Upside: Investor receives 30% equity of the appreciationWhich option do you think is more attractive and why?

In terms of your grandfather living there as long as he's not the owner having a dwelling fire/rental property insurance policy is appropriate.As @Greg Scott pointed out he should have a renters insurance policy whether or not he's actually paying rent.In terms of liability coverage, that depends on what you have to protect so there's no one-size fits all approach.
