I know the struggles all to well with those expensive markets.

Turnkey through a marketer is too expensive and you living there where the action is a big advantage over your brother in CA.

Instead, interest is accrued into the loan balance and paid at maturity (when the borrower either sells the property or refinances the loan).

I've included an example below to help illustrate this.So different lenders have different rates (which do vary even for DSCR loans) but these are factors they all consider.See example below:DSCR < 1Principal + Interest = $1,700Taxes = $350, Insurance = $100, Association Dues = $50Total PITIA = $2200Rent = $2000DSCR = Rent/PITIA = 2000/2200 = 0.91Since the DSCR is 0.91, we know the expenses are greater than the income of the property.DSCR >1Principal + Interest = $1,500Taxes = $250, Insurance = $100, Association Dues = $25Total PITIA = $1875 Rent = $2300DSCR = Rent/PITIA = 2300/1875 = 1.23DSCR lenders generally let you vest either individually or as an LLC.

The only way to get $700 and up is if the property is paid off.  

I don't own property in Pennsylvania but one tip I wanted to give is the face page of all your leases showing pre-paids is helpful.

Unfortunately, reimbursement for expenses (e.g., work related supplies, travel, meals and entertainment) are not considered wages as they are provided for offsetting a specific expense incurred while performing a service for the employer.

I am a huge supporter of Market Leader (used to manage accounts for 40,000+ agents across the United States) and have seen many agents have great success with their leads program, but it is expensive.  

You are calculating around $3600 a month your expenses.
