I have a dog and 2 cats and pretty much have always had dogs and cats so I like animals (we also have a plethora of additional animals: snakes, lizards, fish, frog, tortoise, millipedes, etc. : we are almost a zoo).The tenant that I made give up their "Emotional Support Animal" violated the lease as soon as they had a dog stay at the unit without notifying us. 

If there is a vacant unit, or there will be one soon after closing, what you could do is a leap-frog type of plan where you renovate one unit at a time, starting with the vacant unit.

Buying stuff for the sake of buying it once you have a lot of things it doesn't really matter unless people put their worth on that kind of stuff which can be a hollow existence in and of itself.

Eat That Frog - Short book about taking on the most important tasks first each day. 

Yes, 10,000 people died from it - but 59 million people in the US were infected. .02A% mortality rate.You saying "there's only been (insert wrong number) of deaths so far" is similar to the frog in the warming water pointing out that it's only slightly uncomfortable so far. 

keep cash flowing, there's no rush your doing good no need to play leap frog when your plan is working, before you know it you will be right where you want to be and without taking heavy risks

This prevents the cable installer/satellite dish installer/etc from drilling holes on outside walls to every room (which is what happened in the house with the wrapped coax).Door slabs are cheap and easy to replace as opposed to a framed door...you may need a planer to get them to fit (plane both sides on hollow core doors to prevent splitting).Big box hardware stores are expensive...get an account with a company that supplies real estate investors and/or contractors for decent cabinets, appliances, and other basic supplies.

You know what,... frog it.here you go:AND this doesn't include smoke signals either!!!!

Does it just take kissing a lot of frogs to find a prince? 

Those doors are of course hollow but solid doors can be had and the screws changed out with longer ones to prevent the wood from splitting, or at least prolong them from splitting out.
