No, it was a single 30-day stay.Proof is not required when you file your taxes.

We're hoping to do seller financing when we buy our first rental investment property, so I'll be hand-writing letters to long-time owners of rental properties (mostly single family or small multi-family).

So in 3 years - your single house is worth $151,510.  

Only future will tell if it was a right investment or not.I am Rao a newbie investor with small rental portfolio of single family homes in DFW area.

We signed on August 17th, 2021, and I had the funds from the HELOC in my account on the 23rd.

Currently occupied by a section 8 tenant on a year to year lease. currently paying $1805Cash flow = $800- I left out some CapEx expenses in the report, as this is a newly renovated home, but will account for everything once I dive deeper into this potential investment.

Lately, I've been torn between investing in multifamily or single-family properties.

I used to use Stessa for financials....but it broke with the more properties and more accounts I linked to it. 

I'd keep that in place.You should account for it even if your doing the work.You should also have cash reserves in case the estimated numbers are off.

Also look to see how many are single family homes vs. multi-family.
