If you put in the effort to source the right opportunity, you’ll find a way to fund it—even with minimal personal cash investment.It sounds like you already have the skills and experience; now it’s just about structuring the right deal.

Personal money How did you add value to the deal?

I personally have a separate account for each property I own.

I have sold some properties years ago on lease options where the tenant buyers actually exercise their right and purchased the property. ( I was in the deed.)The reason I am concerned to tie another person’s property up  with the lease option is that people can change their mind, as in the seller.  

However, I'm short on cash (will be putting $20k of my personal money into this)  and I am exploring creative ways to source funds for the project.I’ve been quoted for a $100K HELOC on my primary residence with a 30/1m ARM at a 13.25% rate and APR, with an interest-only monthly payment of $1,016 and $3,825 in points.

It’s a business account and I just checked, paying 3.95%, more than my personal one!

I have not done it personally but have some insight, maybe my reply may boost your post to someone with more experience in it. 

If you truly have cashflow to spare I would personally look at the 15 year.

Hard money lenders focus more on the property’s value rather than your personal debt to income ratio (which traditional banks use) allowing for quicker approval and funding.

It is also worth noting that property management is often closer to 30% of gross rent for a short-term rental due to the much more intensive hands-on management compared to a typical 10% for long-term and as such, I agree with recommendations above that medium term rentals may provide the best of both worlds if you are able to tailor proximity to a local need, e.g. hospitals and travel nurses.Again, happy to relay my personal experiences in the area if you're interested.Best of luck,Patrick
