@Patrick Roberts & @Tim Delaney- which lenders/ loan types are good for 80%?

Consider a 15 year loan.

Even after one year, that property may provide thousands of dollars worth of appreciation, you will pay down your loan and build some equity, and you can depreciate the asset. 

I am bullish on the FHA 203k and home-style renovation loans that allow you to leverage the cost of your renovation as part of your mortgage, which is just an insane deal, in my opinion.Do you have a specific area where you want to purchase?

I've managed to secure the loan for the new house without having to sell the old house first.

The good news is you don't need a specialty loan for a house hack, just a traditional primary home loan.

@Jordyn Ohsnot enough info to helpbut if you're using a HELOC for the down payment AND getting a loan, then you're probably negative cash flow given that's 100% leveragei would never do that unless i were going to refinance in the short term

If the other two parties want to flip a house maybe they can do just that as partners and then sell you the house which you can buy with a primary home loan with low down payment.

Build - rent - refinance -repeat. in columbus ohio you are buying old houses that are 1900 or 1920 or 1940 and you are in a sellers market. on the other hand you can source land which is a buyers market and build single family homes or duplex or triplexes that will return by renting and pulling cash out on a DSCR loan and doing it again. there aren't a lot of strategies that do this. flipping is different. so many risks. but when someone has a well oiled machine it's all good and less risk.
