Quote from @Rick Im: Does anyone know of a lender that offers second mortgages on rental properties?

He may realize the offer he had was inline with the value.

Right now, the best offers around me are for some 1.3-4 million, that only generated around 100k per year gross, so there would be a high chance of not cash flowing, and paying money, especially with a commercial loan (these buildings have more than 4 units).I was thinking that although the rental itself does not generate money, I would be able to deduct the mortgage interest, and depreciation from my personal w2 income and would be net positive.

The seller is offering seller financing at 2% interest with a 9-year balloon.

At the time, his offer was low, and I had potential plans for that space, so I turned him down.

Steadily has their own product (with multiple writing companies) and then they offer policies through other carriers just as an independent agency would. 

Your maximum allowable offer. 

But if your goal is to leave your day job soon, multi family will offer more cash flow typically.

Which platform offers fresher data for wholesalers propstream or property radar.

Lots of us are happy to offer suggestions but I think we need to understand your situation better.All the best!
