I’ve seen other posts about using a heloc for buy and hold.

Depending on the level of rehab needed, you might be better off using a hard money loan or other construction loan offered by a bank then quickly refinancing it once the work is done.

Newbie here under contract for my first vacation home to use at STR!I can put 10% down-payment using my HELOC (interest payment $113) with a PMI ($142) or 20% down payment for $225 —Mortgage rate 30-year is fixed at 3...

Does anyone know of other good lenders in California that are OK with using a HELOC for down payment?

Looking for thoughts on different ways of using a property management/ leasing agent.  

A typical commercial loan (which will probably want the property deeded under the LLC anyway vs personal name) will likely be much better than using a high interest hard money loan (which are often meant to be short term [6-12 months]) or worrying about a private money lender.

But if I absolutely have to use front end leverage I'd make sure I'm using a fixed rate 30 year. 5.

I did have to end up using a private lender on that property because my conventional loan fell through on a technicality.  

Second, do I acquire using a subject to or a lease option? 

Did you end up using a Canadian line of credit because TD said no, or just because you had cheaper money available?
