Your situation would likely be less even if you paid for tax advisory since you have 2 properties. 

They get paid only if the deal closes, so their interests are not the same as yours.

Tack onto this, legal fees, preservation, taxes paid, etc and you'll likely be over 600K total judgement.   

I don’t have any affiliation with them, just thought I’d share as I think it is pretty much as cheap as you can find for paid softwares with good functionality.Payments take several days to process, but tenants can automate them which is nice.

Assuming the final price is enough for all parties to be satisfied, you'd do a JV agreement with the wholesaler and the realtor would be paid their commission (as opposed to a separate JV).

.- Is there a kind of person who could help me with pre-sale improvements (roughly saying, to tell me what is worth replacing, improving, etc and what is not,1 to make the house more attractive for the buyer)?

It will also be a great loss for those who paid full retail when market reached the pinnacle, they will be upside down and their homes will go on foreclosures.

I am a full time real estate professional and my spouse as a state employee W2 paid job.

Remember: Once you close the seller will get paid, guaranteed!

I’ve updated my listing to remove the reference to the fee and selected the paid parking amenity but I’m not convinced that they won’t delist my properties in the next 7 days.
