Supply: The availability of MFH is considerably lower compared to SFH, which can pose a significant challenge when searching for the "perfect" property, especially when personal needs come into play.

TIA I look at these things the most when looking for BRRRR cities - Rent-to-Price Ratio: Look for cities where the average rent is high compared to the average mortgage cost- Population and Job Growth: Focus on cities experiencing steady population and job growth, higher than national average- Availability of Distressed Properties: Look for cities with a supply of pre-foreclosures, short sales, and abandoned propertiesNormally bigger cities in those states should do well, houses are still somewhat affordable (comparatively) and if you do a big rehab it'll pay off

In that case, i am capable of covering the 20% down payment and closing cost with the money i saved up.

I haven't used Buildium, but I DO use Baselane and it is capable of what you're asking, and much more.

The investor just has to supply a $500 maintenance reserve with the PM to cover any of the smaller issues that require immediate attention.

Your cleaning person should also let you know if you are short or need supplies (i.e. toilet paper, soap,etc) or if anything is broken or missing.I would create a checklist for the cleaning person of what they need  to clean every day, what needs cleaning once a week, and what needs cleaning once a month. 

Here's a PARTIAL list:Office rentComputers, printers & softwareInternet & phone billOffice furnitureOffice supplies: paper, postage, ink, etc.Office liability insuranceAuto expenses: monthly payment, insurance, gas, maintenance, registration/plate feesBroker license fees: annual, monthly board & MLS fees, continuing education fees, E&O insuranceEquipment: lockboxes, signs, etc.Business income tax preparation and paymentsStaff payroll & payroll taxes Time Tasks: answering phones, calling past due tenants, scheduling tours, taking marketing pics, processing those pics, writing ads, researching rent amounts, posting ads, explaining to owners how rent determined & showing where ad posted, opening & processing mail, posting payments, bank deposits, scanning documents & posting to owner & tenant portals, explaining accounting to owners so they understand their monthly statements, taking pics/videos of repairs, finding reputable handymen and contractors, confirming they're properly licensed & insured and tracking annually, verifying repairs done properly, processing invoices for utility bills, repairs, taxes, city inspections, scheduling periodic property evaluations/inspections with tenants that don't want strangers in their homes, explaining to owners why taking so long, and more & more & more...

Other advantages include value add, tax benefits, capability to legally avoid paying taxes on extracted money, and ideally cash flow.  

I could see this being useful in a BRRRR scenario, but in that case you could be looking at a much longer term loan than 30-60 days, especially given supply chain issues and the uncertainty of the person being able to qualify for the cash out loan as rates continue to climb.

I think it is more cost effective and has the capability to put entire SOPs online.
