If a landlord services their AC like they supposed to you will have fewer problems.Joe Gore

Letting him see you making 10k for only a couple days work will be dangerous.

However, using a three-prong adapter to plug in three-prong devices into two-hole receptacles is a code violation (because it can be dangerous), so don't go this route.If you decide to upgrade the main electrical panel, the electrician should use AFCI breakers for the bedrooms, as Jon suggested. 

Fewer properties = fewer tenants = fewer headaches.

If you are planning on using the Renovation loan be aware that fewer lenders do it, while most will be able to do the HomePath Mortgage.

For condos HOA fees tend to be VERY stiff (yes, much fewer repairs, but still...).

It states it was unsafe and dangerous.

I don't have any magic number I buy with cash and have 10/25% of purchase price on hand for what ever comes upI try to have smaller SFRs with fewer tenants less problems.

I personally go all out with this step, because I am just fluent enough with CAD to be dangerous.

I'm not an expert, but as-best-os I know, there shouldn't be any danger.
