Just did a renovation where we took it to the studs and sisters all the 2x8 2 me fl- floor joists with 2x10's for strength, also replace 2nd fl headers as they were insufficient- had a structural engineer come in for the weight calcs for headers and submitted with the revised permit- sounds like you aren't a GC and advise you hire one so it's done right- you have too much work to not do that and understand code.  

Again, you have no body else to pursue because you bought via quit claim.

Just a matter of weight it up and costs associated with this.Alternatively,  start scrubbing, get the sucker pristine ... just joking.Seriously if you have a great tenant and pays on time, just bump the rent up on next lease renewal to cover costs.... win/win

I just talked recently to my sister-in-law with a similar issue you can't just add on anything about the trampoline to the least you can't do that legally she's a real estate attorney you can't legally add it on and technically a trampoline is not a toy it is a workout type of machinery it's almost like having a set of Weights outside or a punching bag if it's not specified already in the lease before you gave it to him legally there's nothing you can do and it would be extremely illegal to just add it in after they were already there and sign the lease you can't add into the next lease it's not how it works now if you had a apartment complex that would be different but if you're renting a home would they put in their backyard is none of your business they're renting your the home from you you can't control somebody's yard you can say yes you need to keep it clean but you can't tell them they can't have a trampoline or a swing set or any of the above in their backyard if they're running a home from you by law.

Good property managers are worth their weight in gold.  

Not giving legal advice, but my understanding of the Uniform Electronic Transactions Act is that digital copies of a signed contract carry the same weight as the original copy.

You can then use this money to continue expanding your business.There are a number of ways that you can use financing to cover your construction costs for renovation, but it's important to weight the pros and cons of each.

I don't want to answer questions at 11:30 p.m. on a Friday, or deal with upset neighbors or regulatory bodies or cleaners or handymen or keypads gone awry, etc, etc.I had a property manager tell me that I have a few big faucets, and he has a bunch of tiny faucets.

Banks/financial institutions/servicers have regulatory bodies that hold them accountable for the proper and appropriate servicing characteristics of their portfolio.

Is there a certification body that checks your financials ie income and net worth and you get certified?
