All investors should consider private money lending as an additional income stream if due diligence is done correctly and the project is a good fit.

I don't know about you, but in 30 years I'd rather be sitting on a million-dollar asset that I own free and clear (because someone else paid it off for me) that is generating multiple, multiple times the rent I was collecting when I first acquired it and in which I can fill a vacancy with a qualified tenant within two weeks because the area is so desirable that it can't keep up with housing demand than on some boondocks asset that I only purchased because it was the cheapest thing around and "cash flowed" $200 per month on paper but barely appreciated over the years and whose rent appreciation has marginally kept up with inflation and takes me three months to fill a vacancy with a "qualified" tenant who even then might get behind on rent because his hours were cut at the gas station 30 miles away (true story; my tenant worked at a gas station in Boron--only job he could find).Personally, I'm keeping my 4-unit in Santa Clarita and investing in development deals and notes until an incredible off-market deal lands in my lap (keep dreaming, Logan) or the SoCal market cools.  

Additionally, ensure that you're well-versed in local market conditions, property values, and renovation costs to accurately assess potential deals. 

So if the investor-friendly agent platform does that I would take that route in addition to many other routes. 

They contributed to additional stress, liabilities and spent energy and money at times throughout my ownership.

Additionally, you may qualify for FHA Down Payment Assistance, where it's truly a grant and NOT a silent second mortgage (avoid these at all cost, in my opinion).

Moving out of state, moving closer to work, school or moving into a bigger home due to expanding family like "pregnant" and/or requiring additional rooms or larger GLA.If you purchase a 2-4 unit and try to purchase another 2-4 unit if they are not "Common" to the area you will have a hard time.

The house is a 3b/2ba 1,895 sq ft home but an additional sunroom built in which brings sq ft up to 2,055 (based off tax records my agent found).

I would like to sell these properties to acquire a larger building, perhaps a 4-unit or larger (maybe commercial), priced around $1M to $1.2M.

Only sell if you have to, or you can move the money to another investment that can produce a better return.If you keep it, you'll have additional income for life.
