It's based on your down payment (LTV) and your credit rating. 

That is why you tend to see builders offering such a big "Builders Credit" it’s because it's "Ghost Money" it really doesn’t matter or exist to an extent.A builder can go into an area build 20-30 homes for example, buy the first 2-3 homes paying top dollar so they can set the market sales.

I’ve seen folks inquire a lot about “cost” be exorbitant but it’s not for the world to set the payroll of the persons assistance they are requesting of.On another note, with that good of an LTV and DSCR - if credit is in good shape you should be in the low 7’s todays market.

Also, for purchasing your rental property you can get 80% financing very easily with no Tax Returns via a DSCR loan, depending on your credit, and Down payment, you could see rates from 5.99-8.99%. 

Hello,My wife and I have been seeking a business line of credit to help us out with paying some debt we've accumulated through our real estate investing and to help with establishing some capital. 

Hey Ryan, Depending on LTV, Loan Amount, Credit and Experience, you can an expect rates from 5.85%-8.9% Subject to points, fees, etc.. $4k in fees is not bad for this loan assuming this is a $100k loan amount.

I’m usually taking out 0% interest for a year credit card loans or 401k loans to find the cash.

DSCR lenders loan on the cash flow of the property more than your credit so they are often a good choice How fast can you save?

To give them credit, there are so many rules and regs for any county, it's impossible for the one person you happen to get on the phone to know everything.So just to be on the safe side, you probably should give them a call again to get some clarity on ALL of the requirements for renting out a basement apartment. 

What documents do they require, what credit scores do they allow, how do they verify previous rental history, etc.?
