I started up an LLC a few months back, planning on building up a portfolio of rental properties over time, and I was wondering, could I write my home off in taxes (For business expenses) if my fiance lives with me, 'paying rent' (Both our incomes go to the same bank) and is there a way for her to lessen her tax burden by saying she is paying a certain amount each month to me as a 'land lord'? 

Follow the lease to the letter, As Alice Coopers song went "no more mr Nice Guy" is my new motto.I have a challenging tenant myself, inherited and Im in the final stages of eviction (this tenant is a pro - knows the laws and has played the game well).

She is honestly not someone we would have rented to if we'd had control over the situation (it's a long story, but we basically inherited her as a tenant upon closing).

The bathrooms are 30 years old, but the toilets work even if none of the kids that inherited the thing are up to scrubbing them to it presents well during showings to retail owner occupant buyers (anything that's a cheap fix, that wasn't done prior to listing, is GOOD news for you because it's going to scare off the nesting newlyweds that can/will offer a price based on emotion).

I'm very curious as how you found a house with such a low price tag; or did you inherit the property?

This is an inherited tenant.

Just closed on a 6-unit property in MA, which will be a cash cow once it’s turned around. One of the tenants, who’d been there living alone, passed away 6 weeks ago. The tenant has a daughter, whom my property manager...

Inherited tenants history of evictions.   

The attorney mentioned that she would draft the operating agreement to protect my initial investment from future marital disputes (currently single) as the funding for the startup is coming from an inheritance.
