@Yongjian PanThe treatment of expenses is different depending on if it is a personal residence or an investment property.

Hoa is now trying, but didn't do much for a year, and so far has claimed all they can do is send notices to the tenant and owner of other units (but, are now saying the they can request proof of treatment - although no idea what can be done if the other owners don't provide proof).

I would offer an initial treatment to satisfy the tenant's immediate concern but let them know that keeping the bugs out of their home is their responsibility.

I would avoid this kind of granite, especially when installing an undermount sink and/or a complicated edge treatment in a property with numbers like the ones you're talking about.Now if you were in MY situation, in significantly cheaper single-family properties, I almost always go for laminate countertops, and I usually make them myself.

A lot depends on how well the house was rehabbed and if preventative maintenance is done ...preventative termite treatments or making sure the soil is graded and gutters are clear and hvac/A/C serviced regularly.

If they are German roaches, a few days after treatment, you have to go in and clean up the dead bugs.  

The best treatment for me has been this forum!

I know when I was a tenant my landlord made me hire professional cleaners, carpet cleaners and flea treatment, etc with receipts.

Had a potential tenant ask me if I did monthly pest control treatments on property??  

I have been doing it for years and have a treasure of info about market rent, deposits, utility treatment, PM's, owners, pet policies, average stay, and empty days.If I were you I'd aim to have two months of mortgage payments liquid, and a plan for how you can quickly come up with two more months if needed as a safety net for unexpected repairs, lost rent, etc.
