This could help secure a higher LTV while you build STR rental history.

IE securing them paying tax's insurance etc etc. 

I completely agree with @Ashish Acharya's points about the cost-effectiveness of a HELOC and the potential credit implications if it’s secured by your primary residence.

Ask for higher security in person have them back out on their own if they still want the place you will be safer with more security

They didn’t completely destroy the house, I did keep most of their security deposit and used it for the repairs, along with some of our own cash.

This setup ensures every project stays on schedule and within budget, which is huge in a market where timing is everything.3.

Consider all the things that could go wrong and see if the lease addresses them: unauthorized pets or tenants, early termination, security deposit, lease violations, late rent, eviction, lawn maintenance, parking, etc.5.

With careful planning, you can develop a portfolio that consistently outpaces inflation and helps secure your financial future.I hope this helps.

Even large and small businesses with intangible residual services like TV, internet, security, pest control or the local contractor with remodels in process could fall behind on payments revenue contract. 

Quote from @Alan Mills: Got an inspection objection back with something I’ve not seen on my other rehab’s (this is a Colorado property):“The seller agrees to have a licensed plumber install external sewer cleanouts per city code and scope the sewer line ensuring its integrity.”This was a full interior/gut rehab and almost everything is brand new.
