So they price those homes at what a willing homeowner will pay for their personal residence.

In addition, you want a separate bank account for the rental property to separate it from your personal accounts.

Living in one unit and renting out the others allows you to deduct 75% of expenses like mortgage interest, property taxes, insurance, and shared repairs as rental expenses, while the remaining 25% applies to personal use.

I personally believe that a better way to jump into mid term rentals is to take a course on buidling a property management company or cohosting business where you bring your skillset to the table without the intial investment into all the furniture and leases.

Id personally classify those as three different investing areas. 

The voucher is the most that Sec8 will pay for that person’s rent regardless of where they rent.  2) The second part of the Sec8 equation is the market rates for specific neighborhood’s and property types (SFR vs apartment, # bedrooms, # baths, utilities included vs paid by tenant, etc).

If the IRS has a Form 1098, they assume that the person listed on the form made the payments, and they move on.
