Am I Crazy? Advice Requested

[Eric D.]

Hello BiggerPockets community. I've been a member now since 2015 and have always valued all of the information that most often I've gotten second hand from another member posting a question and a bunch of members jumping in to advise. Today, I am the one posting. 

Over the past 13 years I've purchased 3-two family buildings BRRRR strategy one at a time. I've been fortunate, had more or less good tenants with only a few hiccups. That being said I've become comfortable with 2 family buildings and how they operate. I haven't made a purchase in three years and the equity in these buildings as I feel need to be deployed. In one of my buildings I have around 264k to deploy and a typical 2 family is going for 650k.Our market here in eastern Massachusetts is pretty competitive as I bet most of the country is now. As I've gone to 2 or 3 family property open houses it appears 50 or more people are showing up to a 1 hour blocks, and then when the dust settles I am being out bid even after going 100k over asking. I get it, the cost to borrow money is cheap and many people are thinking the same as we are, Tangible/income producing assets. My latest thinking is I may just be looking at the wrong properties, that being the smaller Multi's of which cost of entry is lower with as little at 3.5% down. Instead of buying two 2 family buildings perhaps I should just be buying one larger building and that leads me to the advice request. One question being how much more difficult is it for run a 5 family building than a 2 family building. Has anyone felt that wished they kept their properties smaller. I know building / Fire codes get weird here once you get larger than a 3 Family. And the other question is that, I have found a decently built 5 Family building in my area that is in a great part of town and will probably need a little work. Currently it is fully rented. I did the math and it lists at a low 4% Cap rate. Am I crazy to consider this building? Currently I am in my early 30s and am mentioning that to say I plan on keeping any purchase I make for 25+ years. Below are the current numbers on the 5 Family. I could potential see improving that annual income to103k bring the CapRate to 6.5% once the eviction moratorium ends but that's an unknown. Thank you in advance.
