Others have a deed restriction for 1 year.Either way, you are stating the you will occupy the property as your principal residence for 1 year. 

I have no affiliation with them, but I used to live in that area and got to know one of the principals (Bill Kiilrain) who was a good guy and passionate about what they do.

After about the fifth one I got to the point where I realized I'm just watching opportunity pass me by by not having my real estate license... so I decided to create another exit strategy and get my real estate license (I'm taking the test this Friday 6/22/18).Which brings me to the point of this post; do you know any principal brokers in the greater Portland area that support brokers doing what I'm doing?

These are not amortized... i.e. you don't pay principal.

Hi BP,I need help/would love an example/template of how you all are calculating your net worth and principal pay down on your properties on a monthly basis.  

Listing Price:$ 99,990Down Payment: 20% ($19,980) Closing cost: $5,100Loan balance: $79,920 @ 5% for 30 year termEXPENSES (Monthly):Principal & Interest: $ 429Vacancy $40Water/Sewage: $0Taxes $212Insurance $76.50Utilities: $0Management $144Maintenance $24Trash $0CAPEX $172.80TOTAL : $1,098INCOME (Monthly):Rent 1 bed 1 bath $800 (occupied on 1 year Lease)Rent 1 bed 1 bath $800 (occupied section 8 for past 10 years)TOTAL: $1,600I plan to offer about $87K to sweeten up my cash flow, considering they have already dropped the price before and seller is motivated due to acquiring this property from a deceased family member.

Put it back down on the on principal?

I check the SEC, FINRA, ratings websites for inside information on the principals in the company.

@Morgan Klein say no on principal.

However another option I've heard is to re-finance my principal mortgage to pull equity out and consolidate the downpayment and remaining mortgage amount.
