From what i have seen the purchase price does not variate too much if there are tenants for long term, there are more recent ones or none, but the benefit of it is huge.For anyone who has more experience in Germany reading this please correct me if I am wrong.

Finding good contractors and subs is no easy task and often becomes a trial and error thing until you lock in the good ones and hold on to them for dear life.

yes I am looking at Hubspot and will try their trial package.

They're "trial-and-error"-ing it, or "so-and-so said (whatever)" or something they've done before but squeaked by on because there was enough slack in the deal to make it work.That likely also means they don't know how to properly structure a venture, partrnership, etc. to meet lender requirements when the deal is considered as a whole.Another possibility is that your lending criteria are incompatible with the deal the way it is or needs to be structured to make it work and it should never have been proposed to you in the first place.In general, we find that the best and most successful deals occur when the investors are educated and also when the lenders are educated. preferably the same education so everyone speaks the same language on the same level.

Trial is scheduled for later this year.

Looked interesting from an initial trial post and their followup with me.  

Ive also signed for a free trial with Realeflow and the provide lists as well, do you know of or have any experience with the quality of their leads?

We've split tested tens, if not hundreds, of thousands different variations of either a handwritten yellow letter or a typed letter over the years.

And know too that it may be a little trial and error sometimes too, and that's okay.

Because if you submit a different variation you will not be immediately reimbursed.
