Pay for maintenance.

You’ve developed a moderately fast wealth accumulation strategy that’s relatively low risk, enabling you to ride out down cycles, negative cash flows, unexpected necessary expenditures, etc.  

Be sure to hold a hefty reserve to handle on-going maintenance, capex, taxes, and insurance.

Rent payments from the medical LLC are fully deductible as a business expense, while the property-owning LLC will report the rent as taxable income, which can be offset by deductions for expenses like mortgage interest, property taxes, maintenance, and depreciation.To ensure compliance, document how FMV was determined—using market comparisons, an appraisal, or similar data—and draft a formal lease agreement outlining the terms, rent amount, and responsibilities.

Low cost housing is a huge motivator to change behavior and keep their housing voucher. 

I actually like them because the homeowners' association (HOA) usually covers most of the insurance, and there is very little maintenance required.

Low appreciation may make the RoI from these assets low over long term, though they will cash flow on day 1.

It isn't having paid off properties that offers security, there are still taxes, insurance, maintenance and management involved. 

@Jay Fayz for SFR (1-4 family) Classifications are mostly opinion-based.Not aware of anyone tracking eviction rates, except Evictions Lab nonprofit that doesn't like landlords.Here's some info that might helpt:---------------------------------------------------------------------------------------------------Recommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

With that low interest rate, you will have paid down a lot of equity in the deal and should be able to finance with a bank.
