I did not ask for input on my landlording skills.

I'm not sure the area my property is in would qualify for anything of the things you mentioned.

@Mikky Chanthavong - it depends, apartments with 4 units or less is residential and loans are made to a person using your income and the rents to qualify. 

They can use 25% of the rents to help you qualify, the rest will depend on your DTI ratiosYou can't just use equity in another property for the down payment, you can pull equity out via a loan or line of credit but just because you have value in that property doesn't mean you can use it to buy another 

I am very interested in the BRRR strategy and want to hone my skills on this kind of analysis, but am unsure about how to calculate repair costs with looking online and crunching numbers on the calculator.

Yes it's usually geared more towards the cash buyer who is acquiring distressed properties.Sometimes these properties do not qualify for conventional loans due to their condition.However it would work the same way with a financed property assuming the numbers checked out.

As for my loans, I should supposedly qualify for public service loan forgiveness, so im nor sure id want to pay it all off, though I see what you mean

My husband and I bought our first duplex 2 years almost to the day and we have been working to get our next investment property in the near future.In all my research and education, I've realized that I feel stuck in my current day job and I know my skills are much better suited for the real estate industry.

Depending on your DTI ratio, he may be necessary for you to qualify.

Normally you only go for seller financing if you either don't have the normal 20% deposit, or you don't qualify for conventional, in which case - you're at the Seller's mercy.ie.
