For a turnkey kind of solution it can be very very costly.We have recently been going through the most aggressive rehab project to date (residential rehab) and I've had to learn about masonry a lot more. 

I recently started using Natasha McElderry at Oak Tree Properties and she has been good. 

DO NOT ever take advice from US based companies selling real estate to foreigners, they are not up to speed on the nuances of investing broadly in the US and it's not an one size fits all solution.  

Hi,If you are looking to save money and also a solution to leaking, i would suggest to reinstall roofing with modified bitumen, it will make your space more elegant and attractive, This option is not so long lasting, but is costs less & In terms of durability i would prefer you to go for EPDM method for re-installing roofing.

Solutions?

The only exception to this, in my opinion, is if you have put together a really strong network and have access to buyers/ solutions that the agent might not otherwise. 

Pictured above is lovely old home located dead smack in the middle of the BIG city of Houston... looking at the lot and the ENORMOUS trees you would never think so! 

I place my signs on trees as often as I can. 

I'm going to do some inexpensive facelifting, too, at the property, (trim painting, mulch, and up-lights on trees) so the cool techies from Google will want to live there ;-) And yes I do have laundry on site. 

I think that a solution would be to NOT give up your passion for business, but rather set limits for yourself.
