I've spent quite a bit of time experimenting with a couple of these sites lately.

Claimed that it was 'family members' visiting.

I've heard of mentees who started cleaning up construction areas on a flip at the end of each work day or picking up supplies at Home Depot and delivering them to the job site.

Hello all, just made my account here on the site to get some advice.

Is looking online at sites like LoopNet sufficient? 

I tried to google but could only find vacantion-like sites with exorbitant prices.- 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)?

You can check out sites like Zillow or Redfin to see what houses are selling for and what rental prices look like in your chosen market. 

However, you can log the time you spend coordinating with or supervising the contractor, such as meetings, phone calls, and site visits.

. ($1300 for plans if only a wall--I pay $3500 for a site visit by them and close to full gut of kitchen/baths/door moves/wall removals)  Do not skip the permit!!!!
