@Daniel WindingstadThis is alwasy a popular question and everyone will likely suggest the location they are investing in.

It’s completely normal to feel a bit of analysis paralysis, especially when you’re in a position to make a move.The choice between a short-term rental (like Airbnb), long-term rentals, or a duplex comes down to your personal preferences and lifestyle.

Single-family homes and small multifamily properties are popular choices here.It's also a good idea to connect with local real estate groups or online communities for advice and to find good property managers.

There are many reasons why a cash out refinance is the better choice but there are a couple of reasons a Heloc can be used.

Same time, I can let her stay til the family find new home but afraid if she keep complain after lease is terminated.As I have another project, I am ok if they live quietly but what will be the choice if the lease is over and tenant still live there?

Without a diligent and responsive professional, touring, offering and closing on a prime investment property of choice is less likely.

I've worked with investors that have rolled out shipping container short term rentals and they're very popular! 

Both private money loans and hard money loans are popular alternative financing options, but they’re different in key ways.Private money loans are like borrowing from friends or family, but on a bigger scale.

I need some advice on which choice makes the most sense starting off?

So, you are left with the choice to proceed as is, negotiate a lower cost, get a concession, or walk away.I would get a quote and request a concession if they aren't interested in fixing it.
