Example is my dad purchased the home for $40K and my brother put $25K into renovating it can he purchase it for $65K if the house appraises for more and avoid capital gains?

How much property damage can he cause out of spite?

Can he really put a valid lien on our house? 

He was wondering, once he has lived in his single-family for more than one year, can he purchase a 4-unit multifamily property as an owner-occupied property, if he just changes his legal address to the new multifamily property but doesn't "live there"?

if a contractor goes and drives a round town too like fax paper get notray can he charge for payment and still has not send any paper work in and permit still not pulled

Can he negotiate to reduce or eliminate these leins?  

Can he charge more than the estimate that he gave me when the job started.

. $525,000 Sale Price-----------> 12% Cap Rate-----------------------------------------525,000 x .12 = $63,000  The NOI may or may not be too far exaggerated or off, can he support this claim with documentation and rent rolls for prior 3 years?

Can he make a ruling WITHOUT even looking at the evidence that I had with?

Once his name is added, can he sell it and claim the full 121 exemption for taxes (of up to 250k for single people), since he’s lived in the place for two years and it’s his primary residence?
