She complained pest for which i have to spend thousands of dollars.

, pest control, landscaping, breaking appliances, people are hard on these houses! 

Not a single sign of a termite of any other pest in the framing.I do not know about your 1000 years lifetime estimate, but definitely a lot more than 100 years.Best wishes REdwood is naturally resistent to termites  same with certain cedars and cyprus  when one opens the walls on a CA redwood framed house the wood is generally perfect and 100 years old

For Guys the main things that come to mind are: 1) Property damage2) Neighbor complaints3) NOT calling about repairs that need to be made4) Prolonged turnover times For Girls they are:1) Parental involvement/helicopter parents2) Pest control 3) Security issues (i.e. house is broken into)4) Roommate dramaBoth can be incredibly difficult to deal with for sure.

Per our lease agreement (smoke detector batteries, pest control, furnace filters, mini-blinds, lawn care, whatever,  is/are your responsibility.That is an upgrade we can do with a lease increase of $xx/month.We cannot control the neighbors.After a few months if they continued to make unreasonable demands via the maintenance portal, I'd non-renew them.

What if I overpay, what if there are issues , what if I can’t find another great tenant like I have now, what if I can’t find anything g in my price range, what if I find out there is a lien/mold/water damage/squatters/pest/…………..The what ifs will never stop.

Hello BP members, I am in the process of evaluating 6 unit multi family with tenants in place until Feb 2026. 3 unit ( 2 b 2.5 bath) townhome3 unit (studio 1b 1b) Here are the numbers Asking Price : $725000Down Payment : 25%Seller Financing : 3.5% (Interest Only) 5yr balloon period ( Principal Amount due : $543750)Total Gross Rental Income : ~$81000 annuallyTotal Annual expenses : $45400$7200(Property Management)$12000(Owner Paid Utilities)$12000 (Taxes + Insurance) $2200( Pest control + landscaping) $12000 (Repairs/Capex Reserve )Net Operating Income : $81000-$45400 = $35600Total Cash Invested : $181250(down payment) + $13000 (closing cost) Annual Deb Service : ~$19000(Interest only)Net Income : $35600 - $19000 = $16600Cash flow per month : $1400 Cash on Cash Return : ~8.5%There is an upside potential on increasing the rent on 2B units during lease renewal. 

Quote from @Rachel Seymour-Newton: both credit scores are over a 650 and the woman is a teacher and the man co owns a pest control company that is doing pretty well. 

Yes I believe at this point I am forced to do something to clear the building of any mold allegations because tenants do talk to each other, and I wouldn't want someone to hear from someone that there is an apartment with mold infestation and also that the owner/manager did not take action to remediate the possibility of mold.With that in mind, I think the mold testing to be done, needs to be building wide and not just that unit alone. 

Also add items to your lease that are particular to your property. such as parking, number of vehicles, cameras, pests, lawn care, renters insurance required, whatever.
