Hey, there are some good templates online you can download in xls format.

I've been pulling my $/sqft and ARV from and average of the  online "Big Three",  are they consistently accurate enough to rely on?   

Some resources I would suggest:Read Brandon Turner's book on rental property investing https://www.biggerpockets.com/store/rental-investing-digitalListen to the BP Real Estate podcast https://www.biggerpockets.com/podcastListen to the BP money podcast https://www.biggerpockets.com/moneyshowAttend local REI events https://www.biggerpockets.com/forums/521-events-and-happeningsStart analyzing deals to get practice and check out the  BP calculatorsKeep interacting and engaging with others on the BiggerPockets forumsAll the best,

I am new to this tax lien purchasing and have been to live auctions , I have been looking for online auctions.

I guess I don't have to de-convert, the idea came through researching online about how to buy a condo association.

I have not needed to use any online listings before really.

Contact your county Zoning board, might be able to find details online as well.

If I can link with other people or join discussion or seminars from locals or even online that would amazing!!

From reading online, auctions on average only recover up to 37 percent of the owed mortgage.   

especially at the moment when you have a lot of vacancy (may increase further when you enforcing the rules short term). keep in mind vacant unit don't generate income and it's still a great return on investment (full year of rent vs what incentive you offer). that may keep him more motivated. also, I'd personally help with generating leads for new tenant and have manager mainly helping with onsite tasks (showing, move in, etc) for the short term. considering he's 70 years old as you mentioned, he probably are not as effective as using online tools for generating lead (FB marketplace, zillow rental manager, etc)Originally posted by @Cody Furman:Thank you, Bjorn.
