They are farily easy and do nto require much to get started and the Max LTV is going to be 75% but I have seen some exceptions to 80%.Rates are subject to a few thing like loan amount, property type, number of units, credit score and downpayment.DSCR allows you to purchase with No employment and No tax returns so its a little easier. 

@Ali Mol In a lease-to-own agreement, the $1,666 monthly credit should be treated as a liability (deferred credit) rather than rental income, as it is allocated toward the purchase price.

Some mentees will act as a bloodhound for the mentor, knocking on doors, driving for dollars, scouring the internet, making cold calls, or performing other services that help the mentor find new deals.

DSCR loans are based off of down payment, credit score and either actual or market rents so it helps to supercharge an investor's real estate goals and net worth.

Great credit scores and plenty of income from my W-2 source. 

Reason #1:  If you're not careful even a bad lawyer can get it turned into a purchase, with all of the rent credited to the purchase. 

When getting a DSCR loan whose credit score is the lender going to use?

Quote from @River Sava: Hey April - Refinancing after a year if there's limited equity depends on your goals—lowering your monthly payment, cashing out, or switching loan types.The process usually involves checking your current loan terms, appraised value, and credit situation.

The most expensive exchanges are typically "one offs" done by an an attorney with no economy of scale which is a direct result of little direct experience.However I'd also counsel that you not simply look for the cheapest "fill in the boxes" internet intermediary either.  

For example, I mention that every adult must pay a $30 application fee, pass my credit/criminal background, make a combined income of 3x the rent, and whether or not the property accepts pets.
