I'm assuming that lenders wont want to extend a business line of credit without rental history to back it up?

Issue is that in the area that I would like to buy in, these types of properties tend to be either at the max price within my range or far above and I’d rather than over extend obviously.

It sounds to me like this is a better flip (even if over an extended holding period) than a rental.      

Property sales here (Europe) can take anywhere from 3-6months to finalize, so even with a hot market I will have the liability for an extended period of time if I decide to offload.

As some states (such as Massachusetts) has extended moratoriums on evictions into the Fall, inevitably they will cross into lease end/renewal times.

Combine this with San Diego’s unemployment rate being higher than the national average and recently an all time high, the long duration of lost STR rents in a high number STR market (we are down over $60k in lost STR rents), the rent eviction moratorium with limited options for the LL to collect delinquent rents, state wide rent control, number of local RE investors relying on appreciation for any return on their investment imply there are many downward indicators.  

Unique situation which required a lot of patience and some terms most investors wouldn't be interested in (extended closing timeline, rent-back to owner after close, etc).

They extend the life of the roof and also reflects heat.

I gave them the option to extend the lease another month since they were having a hard time getting approved for the new property and I sent her an email on July 14th stating the month to month lease will end on 8/31/20 and that the last payment will be dude on 8/1/20 which the tenant replied and agreed to the terms.
