I lived in it for two years as my primary and have been renting since  I moved to SF, mostly via airbnb.

I took out a HELOC on my primary residence that I plan on transferring into my llc to purchase a property here in Denver within the week.

The location (schools, restaurants, crime, etc) is decent but nothing too promising in terms of appreciation (3% annual average) Here are the details: Purchase price: $170,000Rental Estimate per month: $1500HOA: $1000/yrInsurance: $1100/yrTax rate: ~3.4%I assumed the following:I use a 20% downpayment on a 30 year fixed conventional loan w/ 4% APRNew build so warranty is covering most things so minor, if any, maintenance will be neededTake into account 1 month of vacancy per yearTake into account annual broker fee to list of one months rent~5K closing costs~2k in appliance purchasesResult: Assuming rent range of $1500-$1550/month and assuming 1 year I wont have to pay the broker fee to list:From my cash flow analysis I am projecting to have positive cash flow of around .02%-2.1% per year. 

.#5: It's much easier to BORROW to buy property, vs. shares (and STILL obtain positive cash flow).

I have a 2 bedroom/2 bathroom primary residence that I bought with the intention of renting out the extra room.  

like how much down payment would be added to calculate a positive income for a rental property?

This evil bastard has a faulty moral compass and has decided to steal from the "rich" (you) and give to the "poor" (himself) by squatting on the premises under the guise of a non-existent or forged lease.Where I in your position, I'd find a FLAT RATE eviction attorney that has experience with these kinds of cases as soon as humanly possible.

You have to live in the home as your primary residence for at least 1yr OR you can refinance after 6 months to a conventional loan.  

Also for an LLC to apply for a financing, does the lender take into account both (or all) partners credit worthiness or is there/could there be a primary?
