Hello @Sufyan Minhas,What you have in mind is doable.

If it's a massive budget, lenders may peak in a bit more, but definitely doable. 

I have to of a littl bit deeper into the house hacking what properties would be doable for us.Do you have any tips/plattforms beside BP to find meetups?

Meeting the material participation hours is absolutely doable, even with a property manager, as long as you stay actively involved in key tasks like marketing, bookings, and bookkeeping.

Also, would getting a HELOC so soon after be do-able?

That's without figuring in tax benefits, increasing revenue per year with inflation, picking a market with more appreciation potential, making more than $1K/month profit (very doable) etc that could supercharge those numbers even more. 

House hacking a quadplex in Orange County is ambitious but doable with patience and the right strategy.

I feel they are all doable.

That being said, this is mainly doable for folks taking on cosmetic rehabs with great time management/construction management skills.

@Shwetha Pindikuri,Assuming an FHA loan with a second mortgage can be tricky, but it’s definitely doable with the right lender.
