Add in $20,686 in carrying costs (10 months at $2,298), the all-in cost to date is $658,450.Phase 2 of the project is sub-divide the lot into three lots, and add new duplexes to each of the new lots.

The buyer requested a transfer from his job to the city where the house is but now the job wants him to start work next week, I told him we can probably let him and his family occupy the property prior to the closing date.  

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

Another thing I've done is to go onto STR sites, and check out a couple things.

Include the date, duration, and a brief summary of what was discussed (e.g., "Discussed renovation plans with GC for STR property").

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.

I seriously thought the op date would be 2019, or 2015. 

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)?

Is looking online at sites like LoopNet sufficient? 

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.
