Given Covid related material and supply shortages, should I plan additional buffer time around my contractor's estimates. 

Here are a few additional insights that might help as you transition into multifamily:First, when scoping out deals, relationships are key.

The longer the maturity rate of the bond, the higher the yield is to compensate an investor for the additional risk they are taking on with a longer dated bond.Stocks that pay divideneds....insurance companies have a lower yield than telecom stocks as a reflection that telecoms are higher risk than insurance companies.In the efficient market hypothesis, if markets are efficient then the yields should be reflective of the risk.

In addition to my real estate expertise, I’ve spent years building and collaborating with property management companies.

I got a very good price on the building (about $25k per door), but it was a ton of work as in addition to tenant issues, there was TONS of physical distress (foundation repairs, sewer line and water line repairs, electrical upgrades, new roof, and apartment renovations needed for all units). 

Additionally, we will see the unemployment rate tick up another .5%, to 4.9+ maybe even over 5%.   

Additionally we keep the total security deposit until ALL the tenants move out, so the leaving party won't get their security deposit back until the last party leaves. 

Are there any additional fees (e.g., underwriting, appraisal, or prepayment penalties)?

We have had a pleasant and unexpected surprise of some appreciation over the past ten years in addition to rent increases to over $1k for good SFHs.

A good approach is to set aside an additional 5%–10% of gross rent for CapEx, depending on the property’s condition and renovation quality.While turnkey companies often provide attractive numbers, it’s important to remember their goal is to sell properties.
