Unless you have deep experience selling your own properties, there are many details and legalities that can cause you tens of thousands of dollars if not done correctly or if they are overlooked.

I'm only out a small amount and a little time.This would take some work, but I have the experience and skills to handle it.

Best way to find a lender is from someone referring from personal experience . 

You would likely have to owner finance them in my experience to sell them separately. 

We have used GuestPrep, and unfortunately have had a pretty consistently bad experience.

Us bank played trustee and guarantor in sham of a foreclosure where they could not prove they were a PETE  and had been hit with their 4 the ftc sanction FOR stealing homes, used hole in the wall attorneys in Bellingham using typos in name and address to not get flagged for too many foreclosure by the courts, Windermere stellar real estate who say outside of my home waiting to lock me out despite supreme court stay on their theft, judge Lewis who signed every Forged/inaccurate/misleading  paper they put through AND denied my restraining order of the real estate company staying called them to see if they were harassing me and they Said no so denied temp and all together day in court altogether plus put a no Bail hold on me after looking my arrest for trespassing even though was taken out of his jurisdiction and in federal court staying paperwork not filed correctly then laughing saying I didn't know why You're here is in supreme court when I got out of jail and made it to court hearing, the assessor for king county who was on third foreclosure company because feds kept shutting them down so opened new one in different name, every process server was at least 200 miles from me and each one different for each document never served to me but judge Lewis signed them anyways(one was supposedly served to me 3 months before case was even filed), Vancouver Police department who had no jurisdiction on the civil matter that arrested me and gave my house keys to the realtor that was sitting outside waiting, and finally to the site veteran that they used to sign in all three places to transfer title and get veterans protection for title after 2 illegal auctions, one public one private, where they were only bidders and opening bid was above value of house, paperwork stated was bought by lsf8 AGAIN!!! 

You can play around with an amorization table and make an educated guess based on the info found on public record.

After breaking down the pros and cons the one thing I'm not unable to estimate is the appreciation difference between brick versus vinyl property and resale value so my question to experience investors is what would you recommend investing in for appraisal?

If you have any recommendations or are willing to share your experiences, I would greatly appreciate it.As I prepare for the inspection period, I want to ensure I cover all bases and make informed decisions. 

Lean on other real estate investors in your market on who they use - it's not foolproof but working with someone that another investor already had great experience with is a good starting place.Hope all of that makes sense.
