:Class A Properties:Cashflow vs Appreciation: Typically, 3-5 years for positive cashflow, but you get highest relative rent & value appreciation.Vacancy Est: Historically 10%, 5% the more recent norm.Tenant Pool: Majority will have FICO scores of 680+, zero evictions in last 7 years.Class B Properties:Cashflow vs Appreciation: Typically, decent amount of relative rent & value appreciation.Vacancy Est: Historically 10%, 5% should be applied only if proper research done to support.Tenant Pool: Majority will have FICO scores of 620-680, some blemishes, but should have no evictions in last 5 yearsClass C Properties:Cashflow vs Appreciation: Typically, high cashflow and at the lower end of relative rent & value appreciation.

This is the sledgehammer to be used only if this is a major issue for you and you are willing to take the cash flow and renovation impact now.I would do #1 and #2.

This is not only to make sure that people are taking care of the property, but this is also to make sure that tenants aren't overlooking issues that could be addressed now that cost way more later.These can be minor roof leaks, gutter leaks, mostly to do with water penetration.

I had issues with the tenant and we went through a long eviction process.

It is not even an issue of the hours and hours this research takes up.

My mind goes to either1) Sneaky Rental tactic: Upgrade your primary home at prevailing rates, however unattractive they might look relative to your 2.2% rate.

It's all relative.

In the commercial & private money world its all fair game and case by case.Use of credit cards to purchase properties to acquire/capture equity, create, cashflow, provide additional tax shield/benefits against your income, and improve your real estate investing venture is definitely one way to go about it but it should not be the sole method since there are risks like many have mentioned above.If you're using business cards (linked to your FEIN - federal employer identification number) and it doesnt report to your personal credit then it might be more prudent credit wise because your Fico scores won't tank when you max a business card out versus a personal credit card (drop of 80-100 fico pts temporarily till you payoff).So with prudent timing (funds seasoning), knowledge of how to maintain your ficos so you still qualify for your cheaper conventional money, and how to use the cards to purchase can definitely expedite your REI journey.Most people I encounter would not have the know how to do it correctly as I see plummeting fico scores, in ability to qualify, and many other issues with using cards to invest on a weekly basis.Best of luck,

I'm reducing the footprint and repricing.... finally a smart person. our floorplan for each unit we build is 668 sq ft and 2 beds for that exact same reason. people that Aren't in cheap markets don't understand. in columbus we face appraisal issues if we don't keep it as small as possible. 

I keep a capital expenditure account for the big issues, but the rest goes into equity.
