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 = 1.23If a purchase, you also generally need reserves / savings to show you have 3-6 month payments of PITIA (principal / interest (mortgage payment), property taxes and insurance and HOA (if applicable).

You don't need to know everything to get started; you need a foundation to build on, and the rest will come through experience and then refining your education.You can build a basic understanding of investing in 3-6 months.

I would guess that they'll give people a month to apply, but I'm unsure.

I may be wrong but you cannot refi unless the property is seasoned for 12 months when using Fannie, Freddie, Ginnie.

The only item I would suggest is double check the payment terms of the your HELOC... in particular, can you pay interest only or are you required to pay a portion of principle each month on the amount utilized.

Quote from @Brandon Croucier: 12 or 24 Month Bank Statement is probably the best bet.Where would I get one of those? 

How many showings have you had in two months? 

Three Months ago, low to mid 6's were available.Rates are going to continually fluctuate but if you have a way to earn 10+% on your capital, the TIME you are not using it is going to cost you way more than the extra .5% per year will.You are walking over dollars to save pennies if you are waiting for the perfect rate, half of the people who held out on getting mid 6's were waiting for high 5's.

First one defaulted and keep in mind they were maybe 8k a month positive.. average payment was 1.2 on the underlying sub to note. 

I own a property management company in WA, including Yakima.Here’s a rough breakdown of costs:- Management: 15-30% of revenue- Cleaning: $100-$200 per turnover- Utilities: $150-$300/month- Maintenance: 5-10% of revenue- Insurance: $1,500-$3,000/yearTools like AirDNA or Mashvisor can give you a solid idea of income and occupancy.
