The loan on this house is $1,200,000.I moved in to my new primary residence by the end of the month.Starting July, my original primary residence was available as a rental and was being shown to prospective tenants.My new tenants signed a lease that began a couple weeks after showing, in July.To calculate my primary residence mortgage interest deductions, i'm using the following formula:650,000 / 2 = $325000 loan from January to June1,200,000 / 2 = $600,000 loan from July to December$750,000 limit / (600,000+325000 total loan value)  = 0.81 multiplier(0.81 * $X first house interest) + (0.81 * $Y second house) = total interest payed i can deduct from my primary residencedoes this look correct?

Last month, I pulled the trigger on getting my first real estate property ever and decided to go with a 4 bed, 2 bath new construction to limit all the variables involved since I am still in college.

I have found that the profit margins are very low in this model if the house is in a C/D neighborhood because you are limited to the amount of rent you can charge for each room.

Knoxville specifically has some rules regarding STR in the city limits, county is a different set of rules (little more lax). 

Reduced loan limits for investors might force many to seek alternative financing.

I’d like to come in as a limited partner.

Interviewing multiple GC's is the best way to operate, but make sure you are communicating to them that you may want to limit their scope of work as you may intend to SUB out some of the work ourself. 

I didn't have enough space in the Title:Novations where the investor uses a Limited Listing that puts them as the primary contact for scheduling showings, receiving/accepting offers and negotiating are brokering without a license.Novations where the investor actually hires a real estate broker to handle the aforementioned for the seller are not included. 

That would reduce the FICA because you're over the limit.2.

Additionally, if he’s legally and financially tied to the property, it might limit his flexibility if he wants to make major life changes, like moving or starting his own investment ventures.Ultimately, the decision depends on how involved you want him to be in the financial side of the property and how much risk he’s willing to take.
