Is there any website i can use to find a floor plan of an existing house even if i dont  own it?

If the numbers you’re hearing were from a property manager and you’re planning to do it yourself you will do much better than what you heard it was doing in the past :)

Outline a business plan, put up investment criteria, creating financial system and invent property management practices.

Planning to talk to owner.

We plan to do a cash out refinance and keep this as a long term hold.

And plan to hold it forever, even if they outlaw STR.

This is your first property and you plan to live there? 

Presently inhabited by tenants with plans to eject them if necessary.

Professionally, I have study and working experience in the German Taxation Laws and know that Taxation is a crucial and vital aspect in any business in any country.I already have property here in Germany and currently planning to expand to Dubai and Miami USA. 

I'd rather not do an entire cash-out refi because I have a much better rate on the property than I could get today.With a 70% LTV planning factor, I'd still have plenty of room for the cash I'm looking for to make the down payment (~125k).Thanks for any help/advice!
