i.e. if I sell my Primary in January 2025, and I cannot find a replacement Primary to purchase (or cannot win any offers) - can I stay with a family member - until I am able to find AND win an offer on a replacement Primary residence? 

Cleaners, google is your best bet 

@Tomer Einy generally neighborhoods with an ARV of about 250-350k are your best bet right now.

What could be the win win situation.

(Usually for someone without a lot of experience, family or close friends are your best bet.)

However, if improvements were substantial then indeed a Cash out refi will be your best bet, and depending on your credit score, and cash flow you will be between 75%-80%. 

I really see Columbus Ohio as an extremely safe bet for the next 10-20 years.

Another comment: A year ago I told someone that marketing to raise money would be 10-15% meaning expect to spend $10-15k to raise $100k and anything under 7% was winning if done at scale.

I think its not a terrible idea at all and should be pretty good idea actually.I'd recommending reading this "House Hacking" book from the BP Bookstore as your best bet for next step and understanding this process!

You can use it as an STR or LTR so rents are more of a win based on options.You want to be able to spread your capital around to more than one big investment especially when your NOI is going to be better on 2-3 versus one!
